The resource includes a brief example, steps to prevent a related injury, and questions for discussion. It includes a graphic that illustrates a group workers lowering materials with a pulley system in a barricaded zone, which can be posted in a central location as a reminder of steps to work safely.

The use of equipment to hoist employees is prohibited except where the employer demonstrates that the erection, use, and dismantling of conventional means of reaching the work area, such as a personnel hoist, ladder, stairway, aerial lift, elevating work platform, or scaffold, would be more hazardous, or is not possible because of the project's structural design or worksite conditions.

The American National Standards Institute has a standard specifically written for arborists (Z133-2012) that allows this use of cranes, but only after a qualified person has authorized it by determining that it is the "safest and/or only feasible method to perform the work or gain access to a tree."

Introduction

Overview of the Curriculum
Unit 1 - Threats to Your Health on the Job
Unit 2 - Tobacco Threatens Everyone’s Health
Unit 3 - Investigating Chemical Hazards on the Job
Unit 4 - Protecting Your Health

Introduction

As you know, work in your trade can be dangerous. Building and construction trades workers — like workers in some other occupations — face a higher-than-average risk of cancer, lung disease, damage to the central nervous system and other illnesses.

Every year, more than 5,000 Californians die from work-related causes: occupational cancers, lung diseases, heart disease, kidney and nervous system disorders. Over 35,000 new cases of occupational illness develop each year in California.

When the hazard of tobacco smoke is added to other workplace toxics, the risk for these diseases skyrockets. Building trades workers smoke cigarettes at a rate nearly 60% higher than the general population. They use chewing tobacco at a rate almost double that of white-collar workers.

Training is essential to protect workers from preventable illnesses caused by tobacco and other toxics. Well-informed workers can make their workplaces safer. The purpose of this curriculum is to provide workers with the information and skills they need to take action to reduce the risks they face at work — risks from both occupational and tobacco hazards.

Your classes offer workers and future workers an important opportunity to learn skills they need to protect themselves. In our experience, workers in the trades want more information about the occupational hazards they face and the options available to them. Instructors share these concerns and recognize the need for a curriculum that focuses on chemical hazards and their short- and long-term health effects.

Over the years, we've improved safety and health on construction jobs by requiring the use of hardhats and by educating workers about workplace hazards, including the dangers of drug and alcohol use. Similarly, by educating workers about the risks of toxic chemicals, including tobacco, we can help prevent the devastating effects these substances have on them and their families.

Overview of the Curriculum


Building Participation into the Classes

The goal of this curriculum is for students to use the information we present to become problem solvers on their jobs. For this reason, we use a cooperative learning approach. Our curriculum encourages students to take an active role in the class. We've designed class activities to give students maximum opportunity to learn from their own and one another's experiences. By sharing their experiences, people learn that they are not alone and that by working together they can achieve a safer workplace. Classroom activities give students practice in planning strategies to improve health and safety on their jobs.

Real-life experiences of workers are at the heart of this curriculum. The curriculum also encourages students to ask questions and express their doubts. Sometimes when students do not get a chance to talk about their questions, unresolved concerns may get in the way of taking action to protect their health.

Dual Hazard Approach

Our curriculum focuses on the dual risks of tobacco smoke and other toxic chemicals at the workplace. Nearly half of all blue collar workers smoke. In the United States population as a whole, smoking is the direct cause of some 435,000 deaths per year from lung cancer, heart disease and emphysema. Environmental tobacco smoke (ETS) — also called secondhand smoke or passive smoking — includes sidestream smoke from the burning end of a cigarette as well as the smoke that is exhaled by the smoker. ETS is dangerous to both smokers and non-smokers.

Smoking and exposure to secondhand smoke take a disproportionately high toll on workers for a number of reasons:

  • Tobacco smoke adds harmful chemicals to those already in the work environment, increasing the likelihood of asthma, other respiratory problems, and even more serious health damage.
  • Smoking damages the lungs' protective mechanisms, leaving the lungs more vulnerable to toxic chemicals on the job.
  • Substances in cigarette smoke chemically combine with other cancer-causing substances in the workplace to increase the likelihood of tumor growth.
  • The hand-to-mouth contact involved in smoking makes it more likely that a worker who smokes will swallow or inhale toxic dust, fumes, particles or droplets that may be in the workplace.
For all of these reasons, our curriculum encourages workers to view tobacco smoke as another occupational hazard.

For example, we recommend reducing workers' exposure to toluene, a highly toxic substance found in many solvents, through control measures such as ventilation or substituting a safer chemical. Likewise, we encourage creating smoke-free workplaces to control workers' exposure to tobacco smoke, which also contains toluene.

Our curriculum emphasizes that employers are legally responsible for providing safe work environments. It encourages workers to view smoking as one of the many job hazards that can be controlled to protect their health.

We also cover the health dangers of smokeless tobacco, such as chewing tobacco. Smokeless tobacco is sometimes used as a substitute for smoking, but it also contains many toxic chemicals and is extremely damaging to health.

Curriculum Organization

We have divided the curriculum into four interrelated units. However, each unit can stand alone, so if you have limited time or already have covered some of the topics, you can choose only one or two units to teach. The learning activities in the second, third and fourth units build on work completed in the previous units, so if you wish, you could use all the units within a relatively short time period — two weeks, for example.

The first and second units require 60 minutes each. The third unit requires 30 minutes. The fourth unit requires 60 minutes. We encourage instructors to allocate more time, if possible, allowing for more complete class discussions. Instructors may choose to adapt the timing, order or content of the units to suit the particular needs of their classes.

The units are:

Unit 1: Threats to Your Health on the Job (60 minutes)

The first unit draws on students' experiences to introduce the basic concepts of how toxic substances, including tobacco, affect the body.

Unit 2: Tobacco Threatens Everyone's Health (60 minutes)


The second unit identifies the range of chemicals on the job that also are found in tobacco smoke. It also discusses the health effects of tobacco use and of secondhand smoke.

Unit 3: Investigating Chemical Hazards on the Job (30 minutes)


The third unit introduces students to the information and skills they need to investigate chemical hazards they may encounter on the job.

Unit 4: Protecting Your Health (60 minutes)

The last unit identifies the various options available for making the workplace safer. It assists students in developing specific strategies and skills for improving health and safety on their jobs.

This Instructor's Manual provides you, the instructor, with the material you need to teach each unit:
  • A statement of the learning objectives of each unit.
  • A PLANNING GUIDE for each unit.
  • A description of the learning activities and procedures to follow when presenting each unit, including detailed INSTRUCTIONS and DISCUSSION POINTS.(INSTRUCTIONS are suggestions on how to lead an activity. DISCUSSION POINTS are suggestions on specific points that should be made during a discussion, either by you or by your students.)
  • Master copies of all Handouts used in the curriculum. (You will need to make copies of these for your students.)
We have also prepared a student handbook (Guide to Toxics and Tobacco on the Job) for building trades workers. This contains technical and legal information that will be useful to students both in class and on the job. Please encourage students to read the Guide and save it as a reference.

    Introductory Presentation
    UNIT ONE INTRODUCTION (5 MINUTES)
    [Distribute Guide and Handouts 1, 2 and 3 to students at beginning of class.]

    Instructor Explains
    • Every year more than 5,000 Californians die from work-related causes: occupational cancers, lung diseases, heart disease, kidney and nervous system disorders. More than 35,000 California workers become seriously ill from work-related causes each year.
    • Training about health and safety is necessary to protect workers from these illnesses. Well-informed workers can make their jobs safer.
    • The purpose of today's training is to provide information about toxic hazards you face on the job, including the extra risks from tobacco smoke. We're going to discuss the basic ways toxic chemicals affect the body, and look at some other ideas about job health and safety.
    • One toxic we will emphasize today is tobacco. Every year over 400,000 Americans die because of tobacco use. Tobacco is the largest preventable cause of illness and death in the United States.
    • Most people don't think of tobacco as a workplace toxic. However, the effects of tobacco are not confined to the smoker. Secondhand smoke causes over 53,000 deaths a year among non-smokers. Worse news for trades workers is that cigarette smoke interacts with the other toxics on the job to create extra risks.
    • We will be looking at this problem by doing two activities. Are there any questions? Let's begin...
    Activity 1
    VOICES FROM THE WORKPLACE (30 MINUTES)

    Instructions Explain to the students that the purpose of this exercise is to "break the ice" and get them to express their views on health and safety issues. Remind students that there are no right or wrong answers, so it is important to respect everyone's opinion. The exercise will be more effective if you encourage debate.
    1. Students Fill Out Handout 1 Depending on the size of your class, have the students pair off or work in groups of three. Ask students to mark the appropriate space: "Agree," "Disagree," or "Can't Decide" for each statement on Handout 1, Voices from the Workplace. Emphasize that this is not an exam.It is only a way to start people thinking about these issues. Students will keep the handouts; they will not be collected. Students should NOT write their names on the handouts. Let the small groups know they will have 10 minutes to come up with their responses.
    2. Write Down the Student Responses and Encourage Debate

    After the students fill out Handout 1, write two headings on the chalkboard or butcher paper. These headings should be: AGREE and DISAGREE. Read the first statement aloud and ask a representative of each pair or group to give a reason why they either agree or disagree. Write their reasons on the chalkboard or butcher paper. Alternate between asking for an AGREE and DISAGREE response.

    Checkbox Agree Checkbox Disagree

    The point here is to encourage discussion. Encourage the students to explain why they agree or disagree with the statements on Handout 1. Repeat the process for each statement.

    3. Go Over Each Statement and Add Additional Key Points Once the students have quickly noted their reasons for agreeing or disagreeing with each statement, go over each statement and add additional key points that have not been addressed.

    See the DISCUSSION POINTS in the Instructor's Copy of Handout 1 to help introduce some basic information about how toxics affect the body and other health and safety issues. It is best for these points to emerge from the students' discussion, rather than for you to lecture to them. Acknowledge students for the important points they have already covered in their responses.

    During the discussion of Statement 1, ask the students to look at Handout 2, the Material Safety Data Sheet (MSDS) for toluene.
    4. Discuss Handout 3 Ask students to look at Handout 3, Some of the Chemicals in Cigarette Smoke. Ask if students are surprised at how many chemicals are in tobacco smoke. Do they recognize any as being toxics found on the job, as well?

    Voices from the Workplace (Instructor's Copy)
    Handout 1

    1. "Wearing safety equipment slows me down, so I never wear a mask or respirator unless I really smell stuff." Checkbox Agree Checkbox Disagree Checkbox Can't Decide

    Discussion Points
    • Respirators and other safety equipment can be uncomfortable and slow you down. But smelling a chemical is not a reliable way to find out if something is toxic. Some very toxic chemicals have no odor (and you cannot see them, either).

       For example, carbon monoxide has no odor. (Other chemicals, such as hydrogen sulfide, deaden the senses, so you stop noticing the odor after a while.) On the other hand, some chemicals, such as acetone, smell awful, but are not very toxic. The law requires employers to make sure workers are protected against any toxic chemical in the workplace by installing proper ventilation or supplying the proper respirator.

      Ask the students to look at Handout 2, the Material Safety Data Sheet (MSDS) for toluene.

       Handout 2 is a sample MSDS. MSDS stands for Material Safety Data Sheet. Under California's Hazard Communication Standard, as part of workers' "Right to Know," Cal/OSHA requires employers to make MSDS's easily available to their employees. There should be an MSDS available for each hazardous substance used on the job. MSDS's are usually not easy to read, but they can contain useful information.

      Toluene is found in cigarette smoke as well as in workplace solvents.

      Ask the students the following questions:

    • Look at Section 3 on Hazards Indentification. How can this toxic chemical enter your body?
      Make sure the students mention the three routes of entry: inhaling, swallowing, and absorbing through the skin. Give examples of each: (inhaling vapors from open can or when applying, swallowing if worker smokes without washing hands first, absorbing through skin if splashed.)
    • What are the long-term effects of this toxic chemical?
      Toluene can cause kidney damage and can aggravate alcoholism and central nervous system, skin or liver diseases. A chemical's effect on your health can be long term, short term or both. Some toxics have no immediate effect, but will do great damage over the long term. (Example: lead.) Other toxics do have an immediate effect, whether you notice it or not. (Example: carbon monoxide.)
    • Look at Section 8 on Exposure Controls/Personal Protection. Does the MSDS recommend wearing safety equipment to protect you and your co-workers from this toxic chemical?
      The MSDS recommends eye and skin protection, respirators and ventilation. Point out that these protective measures are not used around tobacco smoke, which also contains toluene, lead and carbon monoxide.
    2. "I'm being poisoned anyway, as long as I'm breathing all this toxic stuff at work, so why should I worry about tobacco smoke?" Checkbox Agree Checkbox Disagree Checkbox Can't Decide

    Discussion Points
    • The risk to your health depends on two things: (1) How toxic a chemical is, and (2) How much of it gets into your body.

       A. HOW TOXIC IS IT? Example: Both rubbing alcohol and beer can cause health problems if you drink them. But if you drink rubbing alcohol, which is more toxic, your health problems will be much greater than if you drink an equal amount of beer.

       B. HOW MUCH GETS INTO YOUR BODY? Example: Your body may be able to tolerate two beers, but if you drink six beers within a short time, you may get quite sick. This is called an acute effect. If you drink two beers every day, over time you may do long-term damage to your body. This is called a chronic effect.

      THE POINT IS:
      THE MORE TOXICS THAT ENTER YOUR BODY, THE HIGHER THE RISK TO YOUR HEALTH.

    • Tobacco smoke adds harmful chemicals to those already in the work environment, increasing the total amount of toxics you're exposed to, and therefore increasing the risk of cancer, heart disease, asthma, various respiratory problems and other diseases.
    • The hand-to-mouth contact involved in smoking makes it more likely a worker who smokes will swallow harmful chemicals that may be in the workplace.
    3. "If you're going to get cancer, you're going to get it, no matter what you do."
    Checkbox Agree Checkbox Disagree Checkbox Can't Decide
    • Many people can name someone they know who never worked with cancer-causing chemicals, who never smoked, but who died of cancer anyway. We also know people who smoke and live long lives. These cases are exceptions. The Surgeon General and decades of research have proven that cigarette smoking causes 83% of all lung cancers and about 30% of other kinds of cancer. If you smoke, your odds of dying from lung cancer are five times higher than the odds for a non-smoker.
    • It is harder to total the number of people who have gotten cancer because they were exposed to industrial chemicals. But many studies have proven that certain chemicals increase your risk of cancer. There is no doubt that thousands of cancer deaths could be prevented by reducing workers' exposure to asbestos, nickel, chromium and other toxics. When a worker is exposed to one of these chemicals and also smokes, the risk of getting cancer multiplies sharply. The higher your chemical exposure (including tobacco smoke), the higher the risk.
    • Many substances that formerly were thought to be safe are now recognized as being very harmful to health. Some, such as asbestos and lead, have been banned in many products. Workers' exposure to others, such as benzene and environmental tobacco smoke, has been severely restricted.
    4. "Smoking makes exposure to workplace chemicals even more deadly."
    Checkbox Agree Checkbox Disagree Checkbox Can't Decide

    Discussion Points
    • If you smoke cigarettes or have to breathe someone else's secondhand smoke, the risk to your health from other toxic chemicals will be higher. When tobacco smoke combines with other workplace toxics, there's more risk for several reasons. For example, tobacco smoke contains hydrogen cyanide — a chemical that paralyzes the cilia (tiny filtering hairs) in your lungs. That makes it harder for your lungs to filter out other toxics.
    • Smoking means more chemicals for your body to handle. For example, welding on the construction site produces carbon monoxide. Tobacco smoke also contains carbon monoxide, so you are getting a much larger dose. Long-term exposure to carbon monoxide weakens the heart.
    • When the chemicals in tobacco smoke combine with certain other cancer-causing substances — for example, asbestos — the combination greatly increases the risk of lung cancer. An asbestos worker who doesn't smoke has five times the risk of lung cancer as the general population, while an asbestos worker who smokes has more than 50 times the risk of lung cancer.
    • Smoking on the job also increases the risk of fire and explosion.
    Acivity 2
    MAPPING RISKS: IDENTIFYING TOXIC HAZARDS ON YOUR WORK SITE (25 MINUTES)

    Instructions

    The purpose of this "risk mapping" exercise is to let students use their own work experience to identify dangers at the work site and find ways to control them. Students will draw a map or floor plan of their work site. The map should include the major equipment, processes and areas. Students will also mark the location of hazards on the map. There are two steps to the activity: (1) map drawing and (2) discussion.

    STEP ONE
    Drawing the Map of Workplace Hazards (10 minutes)

    1. Divide into Groups

    Divide the class into groups of three or four students each. There should be no more than five groups. Class members who work at the same site should be in the same group. People who have no work experience should be included in groups that are currently on work sites. One person in each group should volunteer to be the "map-maker."

    2. Distribute Materials

    Give each group a piece of butcher paper. Give the "map-maker" a black pen. The butcher paper can be taped to the wall, or students can work at a table and tape the map to the wall when they are finished.

    3. Explain the Activity

    Explain the risk mapping activity and ask the group to draw their maps. Refer to the risk map directions you wrote on the board. (See page 1.2.)
      In black: Ask each group to draw a map of their current work site, a previous work site, or the classroom shop. The "map-maker" should draw a simple map that shows work areas, storage areas, doors and windows (if applicable), equipment, and other features of the work site. This can be an indoor or outdoor work site.

      In red: Once the basic map is drawn, pass out a red pen and ask them to mark in red the places where workers might be exposed to toxic hazards. If people are having trouble, remind them that the map is supposed to show where they are exposed, not just where toxics are stored or used. Give prompting as needed.

      The instructor can also list the following questions on the board to help students focus:

    • Where is each chemical stored? Where is it between storage and use? Where are vapors, smoke, fumes or mists released into the air?
    • Where is a chemical used? Do the people handling the chemical wear protection? Who might be exposed because they don't wear protection?
    • Where do people take breaks? Eat? Smoke? Wash up?

      Students learn from being involved in a lively discussion when they draw the map. Instructors should encourage everyone to participate.
    STEP TWO
    Discussing the Maps (15 minutes)

    Note: A major purpose of this unit is to show how tobacco, as a toxic substance, adds to the other toxics workers are exposed to. During the discussion, be sure to point out exposures to tobacco in combination with other workplace toxics. The discussion should include hazards of at least two chemicals used at the work site. (It's best if the two chemicals are also found in tobacco, but this is not necessary).

    1. Groups Report on Their Maps

    Bring the whole class back together. Ask the volunteer map-maker from each group to explain his or her group's map to the rest of the class. Make sure the student points out the major toxic hazards. The report on each map should take no longer than two minutes. If groups are identifying the same hazards, ask if any group has identified some different ones.

    2. Sum Up the Exercise

    Point out the similarities in the maps — the hazards that workplaces have in common. Compare the students' maps to the Hazard Chart on pages 12-19 in the Guide.

    Refer students to Handout 3, Some of the Chemicals in Cigarette Smoke, which was handed out for use in Activity 1. Ask them to compare the chemical hazards mentioned on their maps to this list of chemicals. What chemicals on the work site are also found in tobacco smoke?

    Collect the maps and keep them if you will be teaching Unit 4 to the same group.
