The main mechanical risks include cuts, lacerations, needle punctures, crushing, and contact with machines, as well as falls from heights, slips, trips and falls on the same level, and trench cave-ins. The main physical risks include noise, hand-arm and whole-body vibration, and heat stress. What is the difference between physical and mechanical hazards? Other hazards such as fire, explosion, chemical burns, poisoning, and cold burns could occur if gases accidentally escape from the cylinder due to mishandling. Improper handling of cylinders could result in sprains, strains, falls, bruises, and broken bones. In the event of a leak, inert gases can quickly displace air in a large area creating an oxygen-deficient atmosphere, while toxic gases can create poison atmospheres, and flammable or reactive gases can result in fire and exploding cylinders. Is compressed gas a hazardous material?Ĭompressed gases can be toxic, flammable, oxidizing, corrosive or inert. This can include medical waste or samples of a microorganism, viruses, or toxins (from a biological source) that can affect human health. What are biological hazards?īiological hazards, also known as biohazards, refer to biological substances that pose a threat to the health of living organisms, primarily that of humans.

Physical hazards are objects which contaminate your foods such as pieces of glass or metal, toothpicks, jewelry or hair.Chemical hazards are harmful substances such as pesticides or machine oils.Biological hazards include bacteria, parasites, fungi and viruses.Physical hazard means a chemical for which there is scientifically valid evidence that it is a combustible liquid, a compressed gas, explosive, flammable, an organic peroxide, an oxidizer, pyrophoric, unstable (reactive) or water-reactive. Allergen Causing Chemical Examples: Chlorine and alkalis.Irritant Causing Chemical Examples: nickel chloride and chromic acid.Corrosive Chemical Examples: Sulfuric acid and sodium hydroxide.Asphyxiant Chemical Examples: Carbon monoxide and cyanide.What are the 4 types of chemical hazards?

Physical hazards are substances or activities that threaten your physical safety. hair, dirt, bandages, metal staples, broken glass, natural objects (bone in a fillet) Scombroid toxin. Cigarette smoke and radon are two of the most common indoor hazards. Other examples include tornadoes, floods, volcanoes, and fires. Physical hazards occur naturally in the environment. Living on a fault line that is prone to earthquakes is an example of a physical hazard. Which of the following is an example of a physical hazard quizlet? There are five main classes of physical hazard namely Explosive, Flammable, Oxidising, Gases under Pressure and Corrosive to metals. Physical hazard are based on the intrinsic properties of the chemical. This includes compressed gases, liquefied gases, dissolved gases, and refrigerated liquefied gases. Gases Under Pressure are gases which are contained in a receptacle (container) at a pressure of 200 kPa (kilopascals) or 29 psi (pounds square inch gauge) or more, or which are liquefied or liquefied and refrigerated.
