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
Photo of Construction Workers “What I like about construction is working outside and working with my hands. I can drive through town and say, ‘Hey, I built that.’ But it’s a dangerous job. Since 1991, in our Local, at least twelve people have been killed. You walk onto a site and you don’t know what you’re breathing, and you don’t know who’s working with what.”

This Handbook Is for Construction Workers

Many of the dangers of construction work are obvious. We’re all familiar with safety hazards like unstable scaffolding, falling objects, electric shocks and fires.

Other dangers, especially chemical hazards, are less obvious. Some are hidden. If you’re doing demolition work and breathe in asbestos, you may not notice any effect at the time, but you can develop lung cancer many years later. Other chemicals have both short-term and long-term effects. You may feel sick
or dizzy right away when you work with adhesives, paints or other materials that contain solvents. If you work with these solvents for many years, they can damage your liver or nervous system. Coal tar pitch used in roofing and roadwork may irritate your eyes and nose right away and may cause cancer years later.

For construction workers who smoke, the dangers are even greater. When your body has to deal with tobacco smoke as well as the dust and other chemicals at construction sites, your risk of getting cancer, lung disease and other serious illnesses is much higher. And the effects of tobacco use are not limited to the user. Secondhand smoke causes over 53,000 deaths a year among non-smokers.

The purpose of this guide is to give you information you can use to protect yourself. The focus is on the dangers of workplace chemicals and tobacco smoke because you probably already know about the common safety hazards on your job. This guide is part of a health and safety training project that teaches people in apprenticeship and vocational education programs how to recognize chemical hazards on the job, including those from tobacco, and how to plan strategies to make the workplace safer.

Voices From the Workplace

Here are some statements about health and safety that you might hear on the job. You may agree or disagree with each one. The information after each statement will give you some facts.
Photo of Construction Workers “Wearing safety equipment slows me down, so I never wear a mask or respirator unless I really smell stuff.”

Respirators and other safety equipment can be uncomfortable and slow you down. But they can also save your life!

If toxic chemicals get into your body — through your skin or lungs — they can cause serious harm. Some chemicals can affect you right away, causing coughing, skin irritation, dizziness or other symptoms. Other chemicals cause no shortterm symptoms, so there is no warning that they may cause serious long-term damage.

Don’t wait until you can smell a chemical to use your protective equipment.

The nose is not a reliable way to measure danger. Some chemicals smell bad, but are safe. Other chemicals have no odor, but are deadly. One example is carbon monoxide — it’s odorless and invisible, but it can kill. The employer is responsible for making the workplace safe. But if it isn’t possible to eliminate toxics from the work environment, personal protective equipment is your last line of defense.

Photo of Construction Workers “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?

If you’re exposed to toxic chemicals at work, the risk to your health will be higher if you also smoke cigarettes or have to breathe someone’s secondhand smoke.

Tobacco smoke adds harmful chemicals to those already in the work environment, increasing the risk.

  • The more toxic exposure you have, the greater your risk. Avoiding toxic chemicals on the job and toxic chemicals in cigarettes are both important.
  • The more toxic exposure you have, the greater your risk. Cigarettes make it easier for other toxic
    substances to enter the body.
Photo of Construction Workers “If you’re going to get cancer, you’re going to get it, no matter what you do.”

If you smoke, your odds of dying from lung cancer are five times higher than the odds for a non-smoker.

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 because the Surgeon General has proven that cigarette smoking causes 83% of all lung cancers and about 30% of other kinds of cancer.

If you are exposed to cancer-causing chemicals on the job and also smoke, your risk of getting cancer multiplies sharply.


Other chemicals (not just those in cigarettes) also 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.

Photo of Construction Workers “Smoking makes exposure to workplace chemicals even more deadly.”

Smoking or breathing secondhand smoke increases the risk from toxic chemicals for several reasons.

First, 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’re getting a much larger dose. Long-term exposure to carbon monoxide weakens the heart.

Also, 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 5 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.

HEALTH PROBLEMS ON THE JOB

Photo of Construction Workers “When I looked over, there was a big cloud. All of a sudden nobody could breathe. I don’t know what type of cleaner it was, some new stuff. It just choked us immediately. The boss and manager were right there. They didn’t say anything.”

How Do I Know If the Construction Job I’m Working on Is Hazardous?

  1. Is there a lot of dust in the air?

    The air on construction sites, especially during demolition work, can contain asbestos, silica, cement dust, fiberglass and wood dust. Most of these dusts can irritate your eyes, nose and lungs. Some can cause bronchitis, asthma and even cancer.

  2. Do any of the materials you work with contain solvents?

    Varnishes, wood sealers, paints, thinners, adhesives
    and many other construction materials contain solvents. They can get into your body through your skin or when you breathe the vapors. Solvents can give you headaches and make you dizzy. If you work with them for many years, they may damage your liver or nervous system.

  3. Do you use any materials that contain polyurethane or epoxy resins?

     Many construction materials — like adhesives, sealants, waterproofing agents, floor and wall coverings — are made up of isocyanate (the raw material for polyurethane) or epoxy resin systems. The chemicals in these systems can get into your body through your skin, or when you breathe the mists or vapors. They can irritate your nose, eyes, throat and lungs. Some people may develop an allergic reaction, similar to asthma.

  4. What are other trades doing nearby?

    In construction work, someone else’s work may produce welding fumes, chemical vapors, asphalt smoke or other toxic hazards. These can affect everyone in the vicinity. Be aware of what other trades are doing, and protect yourself.

  5. Are you exposed to cigarette smoke?

    If you or someone else smokes on the job, you’re being exposed to many more toxic substances. Cigarette smoke contains over 4,000 chemicals.

Construction Hazards

DUSTS Source Health Effects
ASBESTOS Maintenance and demolition work; roof tear-offs. Construction: floor tile, roofing materials, drywall compounds, gaskets, packing materials, electric insulation, corrosion resistant coatings, heat resistant materials, asbestos cement pipe and sheet. Short-term: Lung irritation (if very high levels).
Long-term: Asbestosis (scarring of the lungs); cancer of the lung, stomach, and intestinal tract.
Asbestos workers who smoke have over 10 times the cancer risk of asbestos workers who do not smoke.
SILICA Maintenance; remodeling; demolition work; application of fireproof coatings; sandblasting; tunneling. Long-term: Serious, incurable lung disease (silicosis).
CEMENT Construction and demolition of foundations, sidewalks and floors. Short-term: Eye, nose, skin and lung irritation. Causes skin rashes and infection. Allergic skin rashes.
Long-term: Small decrease in lung function, wheezing, shortness of breath.
WOOD DUST Construction, remodeling and demolition. Sawing: wood, plywood, particle board. Short-term: Allergic skin rash, asthma, nasal irritation, skin and eye irritation.
Long-term: Nasal cancer.
FIBERGLASS
& OTHER
INSULATION
MATERIALS
Insulation on pipes, other insulation, air conditioning. Short-term: Skin, eye, nose and throat irritation; shortness of breath.
Long-term: May cause lung cancer.

DUSTS

CONTROLS FOR DUSTS
ASBESTOS

Asbestos removal jobs may be done only by licensed asbestos contractors.

Isolate asbestos work and provide exhaust ventilation or dust collecting device.

Keep material wet while removing it.

Wear special protective clothing and correct respirators.

Remove clothing and shower before leaving enclosed area.

Post caution signs and labels.

Smoking should be prohibited.
OTHER DUSTS Wear the correct respirator if required (not a paper dust mask).

Vacuum or wipe off surfaces using wet mop or rags. (Avoid sweeping and blowing away dusts to clear surfaces.)

Keep work materials wet where possible when sanding, grinding, sawing, etc.

Don’t drink, eat or smoke in work area.

Wash hands before eating and before breaks.

Change clothing and, where possible, shower before going home.

Use local exhaust ventilation if not working in an open area.

Isolate dusty operations such as sawing and sanding to reduce worker exposure.

METALS
Dusts & Fumes
Source Health Effects
CADMIUM, CHROMIUM, COPPER, ZINC, MAGNESIUM Welding; drilling, cutting and sawing pipes; scraping rust or coatings. Short-term: Metal dusts can be irritating to skin, nose, eyes and lungs. Effects of fumes differ depending on metal (see MSDS). Some metals (such as zinc, copper, and magnesium) cause metal fume fever (flu-like symptoms with fever, nausea, chills and muscular aches and pains).
Long-term: Depends on metal (see MSDS). Cadmium and chromium can cause cancer.
LEAD Cable splicing, demolition, remodeling, painting, pipefitting, plumbing, roofing, sheetmetal, iron work, welding on lead or surfaces with lead paint or coatings; brass fixtures may release lead. Short-term: Effects are very rare. If exposure is high, symptoms similar to long-term effects may occur.
Long-term: Damage to brain and nerves (tremors, muscular weakness, lack of coordination), damage to reproductive systems (men and women), stomach problems, anemia, damage to kidneys.

Isolate dusty operations such as sawing and sanding to reduce worker exposure.
METAL FUMES Avoid welding on toxic metals or coatings; brush or scrub off coatings first.

Natural ventilation is often adequate in open areas.

Position yourself so that fumes don’t blow into your face.

Use local exhaust ventilation in indoor areas or confined spaces.

Wear the correct respirator when ventilation or other controls are not possible.

Lead: Shower and change clothes to avoid bringing lead home to your family.

SOLVENTS

Health Effects CONTROLS FOR SOLVENTS
Most solvents you work with, including acetone, TCE or other degreasers, affect your health in similar ways:

Short-term:Most organic solvents affect the brain the same way drinking alcohol does. Overexposure causes symptoms resembling drunkenness, including headaches, “feeling high,” nausea, dizziness, and at high levels, loss of coordination. Other short-term health effects are eye, nose and throat irritation, and skin rash.

Long-term: Repeated, frequent overexposure over months or years may cause long-lasting damage to the central nervous system (the brain and nerves).
Where possible, ubstitute materials that are less toxic.

Use ventilation to remove vapors.

Wear the correct respirator (refer to MSDS).

Wear proper protective clothing, correct gloves, goggles, face shields.

No smoking. No open flame nearby.

Vapors can build up quickly and become extremely dangerous in confined spaces.

Follow OSHA confined space entry procedures where required. (These include pretesting atmosphere before entry; mechanical ventilation of space; respirators; rescue person.) Many fatalities occur in confined spaces.
