Easy-to-read, question-and-answer fact sheets covering a wide range of workplace health and safety topics, from hazards to diseases to ergonomics to workplace promotion. Read the material safety data sheets for any hazardous products that you use and follow any recommended safety precautions. Add a badge to your website or intranet so your workers can quickly find answers to their health and safety questions.

Personal Protective Equipment: Eye and Face Protectors

Eye wear will protect the user if the eye and surrounding soft tissues are fully covered by the protection device. If eye protection is required, establish a complete eye safety protection program including selection, fit testing, training, maintenance and inspection. Eye and face protection devices need maintenance.

Safety Hazards: Working Safely with Sharp Blades or Edges

Is there a different type of blade or tool that will do the job safer (e.g., covered blades, fixed guards, non-exposed blades, spring backs, tape splitters, pliers, snips, etc. What do I need to know about the safe use of hand tools with sharp blades? Do not drop or leave a sharp tool in a place where it cannot be seen; for example, by placing other items on top of the tool, or by placing the tool in dish water.

Easy-to-read, question-and-answer fact sheets covering a wide range of workplace health and safety topics, from hazards to diseases to ergonomics to workplace promotion. What are examples of occupational exposures that have been associated with exposure to carcinogens? Add a badge to your website or intranet so your workers can quickly find answers to their health and safety questions.

Prevention and Control of Hazards: How Do I Work Safely with - Flammable and Co ...

This document summarizes safety issues related to static electricity, bonding and grounding containers, etc. when using flammable and combustible liquids. Even when liquids are transported or handled in non-conductive containers, something rubbing the outside surface of the container may cause a static charge to build up in the liquid. However, when liquids are transferred into non-conductive containers (e.g., plastic, glass), even conductive solvents may build up a charge because the plastic...

Prevention and Control of Hazards: How Do I Work Safely with - Dangerously Reac ...

For materials requiring temperature control, the recommended storage temperature range should be plainly marked on the container. When transferring materials from one container to another, avoid spilling material and contaminating your skin or clothing. Do not allow materials, such as cleaning liquids, paints or thinners, to come into contact with dangerously reactive materials.

The Young Workers Zone : Teaching Tools : Physical Hazards: Preventing Slips, Tr ...

Many injures occur because people fall on slippery floors or trip over clutter and obstacles on walking surfaces. If the spill is a toxic chemical, use safety procedures recommended in the material safety data sheet. Housekeeping - Keep floors and walking surfaces free of clutter, trash, obstacles or torn rugs in walkways or on the floor.

The Young Workers Zone : Teaching Tools : Physical Hazards: Thermal

Heat rash, or prickly heat, occurs when blocked sweat glands become inflamed. Heat exhaustion results when the body loses large amounts of fluid by sweating during work in hot environments. Indoor workers who work in hot environments, such as foundries, bakeries, smelters, and glass factories are at risk for heat illnesses.

The Young Workers Zone : Teaching Tools : Physical Hazards: Slips, Trips and Fal ...

Spills and slippery surfaces - when a liquids (water or oil) and solids (dust or ice), coat a surface they decrease the amount of traction you have, therefore making it easier to slip and fall. DO NOT LEAVE trash, clutter, obstacles, or torn rugs in walkways or on the floor. Housekeeping - Keep floors and walking surfaces free of clutter, trash, obstacles or torn rugs in walkways or on the floor.

The Young Workers Zone : Teaching Tools : Ergonomics: Standing Workstations

This activity helps to demonstrate the importance of having a workstation that is at the right height. To work at this counter, this person must stoop. The counter is too low - they have to bend their backs to reach the surface and the glass shelf is in their way.

Ergonomics: Lighting Ergonomics - General

Electric Lighting: The amount of light, the colour of the light itself and the colour that objects appear vary with the type of electric lighting. Localized-general lighting uses overhead fixtures in addition to ceiling fixtures to increase lighting levels for particular tasks. The complete lighting unit (also called the light fixture) controls and distributes the light.

Chemicals and Materials: What are the Effects of Dust on the Lungs?

The air reaches the tiny air sacs (alveoli) in the inner part of the lungs with any dust particles that avoided the defenses in the nose and airways. However, in this OSH Answers document, we are only considering dust particles that cause fibrosis or allergic reactions in the lungs. Dust particles and dust-containing macrophages collect in the lung tissues, causing injury to the lungs.

Prevention and Control of Hazards: How Do I Work Safely with - Flammable and Co ...

Never use plastic or glass containers for storing flammable liquids unless storage in metal containers would affect the required liquid purity or if the liquid would cause excessive corrosion of the metal container. Many workplaces receive flammable liquids in large metal drums or barrels, then fill smaller containers from them. Whenever possible, use approved, properly labelled safety containers when working with flammable and combustible liquids.

Diseases, Disorders and Injuries: Work-related Musculoskeletal Disorders (WMSDs)

The tendons of the hand are encased in sheaths through which the tendon slides. Failure of the lubricating system creates friction between the tendon and its sheath, causing inflammation and swelling of the tendon area. The fibrous tissue thickens the tendon sheath, and hinders tendon movement.

Prevention and Control of Hazards: How Do I Work Safely with - Organic Peroxide ...

For organic peroxides requiring temperature control, the recommended storage temperature range should be plainly marked on the container. Some liquid organic peroxides, however, such as methyl ethyl ketone peroxide, gradually decompose giving off gas. For example, methyl ethyl ketone peroxide and cyclohexanone peroxide may explode if they are mixed with acetone, a common solvent.

Prevention and Control of Hazards: How Do I Work Safely with - Cryogenic Liquid ...

Mixing flammable cryogens and liquid oxygen produces a fire hazard. Thoroughly clean any equipment or container used with liquid oxygen to the degree required for use with oxidizing materials. Protect the eyes with a full-face shield (with safety glasses or goggles) if a cryogenic liquid is poured or if an open container of the cryogen may bubble.

Chemicals and Materials: Lead on Construction Projects

installing or removing lead products (such as lead panels, lead sheeting and lead bricks used for shielding radiation sources). Remove lead based products where possible by using safe work practices when removing or disturbing lead (see engineering controls for examples). Respirators prevent the inhalation of lead where engineering controls and work practices do not control the concentration of lead to below the occupational exposure limit.

Ergonomics: Lighting Ergonomics - Survey and Solutions

For example, a covered light mounted under a transparent guard on a grinding wheel provides the added light needed to clearly see the task. Reflectance is the ratio of light falling on a surface to the light reflected from a surface, expressed as a percentage. Next, place the probe 5-7 cm away facing the surface to measure the light reflected from the surface.

Manual Materials Handling (MMH): MMH - General Practice

Easy-to-read, question-and-answer fact sheets covering a wide range of workplace health and safety topics, from hazards to diseases to ergonomics to workplace promotion.
