Dangerously Reactive Liquids and Solids: Dangerously Reactive Liquids and Solids ...

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. When water contacts thionyl chloride or sulphuryl chloride, they decompose rapidly giving off sulphur dioxide gas and hydrogen chloride gas. Highly reactive chemicals may undergo vigorous, uncontrolled reactions that can cause an explosion or a fire, or rupture sealed reaction vessels or storage containers.

Physical Agents: Laser Plumes - Health Care Facilities

Are there any health hazards associated with laser plumes? The CSA Standard Z386-14 "Safe Use of Lasers in Health Care" specifies that facilities using lasers shall have a laser safety officer (LSO) and a laser safety committee (LSC) to perform risk assessments, and to ensure that laser safety policies and procedures are developed, implemented and maintained. The OSH Answers document Lasers - Health Care Facilities has additional information on laser safety programs, LSOs and LSCs.

Occupations and Workplaces: Fire Fighter

This summary focuses on the major job duties that most fire fighters (those fighting primarily structural fires) would have in common. What are some health and safety hazards associated with being a fire fighter? Are there any long-term health effects of being a fire fighter?

Health Promotion / Wellness / Psychosocial: Environmental Tobacco Smoke (ETS): G ...

Environmental tobacco smoke (ETS) refers to exposure to tobacco smoke - not from your smoking, but from being exposed to someone else's cigarette, cigar, or pipe smoke. Since some chemicals are favoured by this incomplete burning, undiluted sidestream smoke contains higher concentrations of several chemicals than the mainstream smoke inhaled by the smoker. This finding implies that cigarette smoke that becomes adsorbed onto the clothing of smokers (third hand smoke) pose a similar risk to ...

Welding: Welding - Fumes And Gases

Welding gases are gases used or produced during welding and cutting processes like shielding gases or gases produced by the decomposition of fluxes or from the interaction of ultraviolet light or high temperatures with gases or vapours in the air. Acute effects include irritation of the eyes, nose and throat, nausea and "Metal Fume Fever. Table 2Source and Health Effect of Welding Gases Gas TypeSourceHealth EffectCarbon MonoxideFormed in the arc.

How to Work Safely with: How to Work Safely with - Hazardous Products Using the ...

Hazardous products with the flame pictogram can be a fire or explosion hazard in the workplace. Below are the signal words and hazard statements for the other WHMIS 2015 hazard classes and categories that are assigned the flame pictogram. Handle and store pyrophoric products and products that react with water to release a flammable gas under inert gas or a liquid/gas specified by the supplier.

Very Toxic Materials: Very Toxic Materials - Hazards

To prevent the possibility of adverse health effects from exposure to very toxic materials, it is important to understand the potential hazards and how to protect yourself. Very toxic materials are capable of causing serious and significant health effects in an exposed individual, including death. Very toxic materials cause serious health effects by damaging critical body systems.

Chemicals and Materials: First Aid for Chemical Exposures

There are some situations where the benefits of emergency oxygen outweigh the potential risks associated with maintaining and storing oxygen cylinders in the workplace. Additional training of first aid providers is required since basic first aid training courses do not include oxygen administration. Be sure that the emergency first aid providers in your workplace have the appropriate training and authority (if necessary) to respond to the effects of chemicals used at your workplace.

Chemical Profiles: Hydrogen Sulfide

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 fire hazards and extinguishing media for hydrogen sulfide? What is the American Conference of Governmental Industrial Hygienists (ACGIH®) recommended exposure limit for hydrogen sulfide?

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.

Compressed Gases: Compressed Gases - Hazards

Thousands of products are available which contain gases and mixtures of gases stored under pressure in cylinders. Liquefied gases are gases which can become liquids at normal temperatures when they are inside cylinders under pressure. When acetylene gas is added to the cylinder, the gas dissolves in the acetone.

Oxidizing Liquids and Solids: Oxidizing Liquids & Solids - Hazards

What happens when an oxidizing material comes in contact with a combustible substance largely depends on the chemical stability of the oxidizing material. The National Fire Protection Association (NFPA) Code 430 (1995) "Code for the Storage of Liquid and Solid Oxidizers" provides many examples of typical oxidizing materials listed according to the NFPA classification system. These oxidizers can undergo dangerous reactions with water, inorganic acids or even other oxidizing materials.

Cryogenic Liquids: Cryogenic Liquids - Hazards

Different cryogens become liquids under different conditions of temperature and pressure, but all have two properties in common: they are extremely cold, and small amounts of liquid can expand into very large volumes of gas. In poorly insulated containers, some cryogenic liquids actually condense the surrounding air, forming a liquid air mixture. When cryogenic liquids form a gas, the gas is very cold and usually heavier than air.

Forklift Trucks: Forklift Trucks - Batteries

When talking about lead-acid batteries, people usually call sulfuric acid "battery acid" or the "electrolyte". If the battery has sealed vents, do not recharge the battery with a current greater than 25 amps. Follow the battery manufacturer's recommendations about when to recharge or replace batteries.

Garages: Garages - Batteries

When talking about lead-acid batteries, people usually call sulfuric acid "battery acid" or the "electrolyte". Consult the safety data sheet for the battery or for sulfuric acid before beginning any work with batteries. Use a cable puller to remove a cable clamp from the battery terminal.

Safety Hazards: Battery Charging

The two primary risks are from hydrogen gas formed when the battery is being charged and the sulfuric acid in the battery fluid. For general safety precautions when working with batteries, please see the OSH Answers Garages - Batteries which covers automotive vehicle sized batteries. Depending on the metal alloy composition in lead-acid batteries, a battery being charged can generate two highly toxic by-products.

Chemical Profiles: Phosphoric Acid (Solutions)

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. Provide eyewash and safety shower if contact or splash hazard exists. 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 - Oxidizing Liquid ...

Organic materials, such as wood, should not be used in ventilation systems for oxidizing materials. If totally separate storage is not possible, store oxidizing materials away from incompatible materials especially organic or other oxidizable materials (sometimes called reducing materials or reducing agents). Keep containers of oxidizers tightly closed, except when actually using the material, to help avoid spillage or contamination of the container contents.

Chemical Profiles: Sodium Hydroxide

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.
