How to be a good safety mentor

- greet the person - give a tour of building and lab - show emergency shower, eye wash stations - safety supplies and waste collection points - emergency alarms - review the map with emergency exists, evacuation, shelter-in-place -where safety equipment is - conduct safety reviews - be a "one stop shop" for questions

signal words, container labels, and safety data sheets (SDSs)

pictograms

standardized graphics (harmonized hazard symbols) which are assigned to a specific hazardous classification or category - convey health, physical or environmental hazard information (Not a unique one for every hazards. One may represent several hazards)

hazard classification

the process of assigning a chemical or mixture to a hazard or danger category based on its health and physical hazards

physical hazard

the properties of a gas, liquid, or solid that adversely affect you or the workplace in a physical way (i.e. fire, explosion, etc.)

health hazard

the properties of a substance or mixture that can cause illness or injury to the skin, eye, lungs, or other organs or body parts

safety data sheets (SDS)

uniformly formatted MSDS that allows employees to obtain concise, relevant, and accurate information more easily - have 16 sections in a specific order

signal words

words "Danger" or "warning" are used to emphasize hazard and relative level of severity of the hazard Danger > Warning (only one word per chemical label)
