1 / 10
Acute vs Chronic - CORRECT ANSWERS--Acute -occur after a short period of exposure and their damage happens quickly -Chronic -occurs gradually over time and from repeat exposure Hazards of chemicals - CORRECT ANSWERS--physical hazard -flammable/explosive, water reactive, unstable -health hazards -nausea, stomach, reproductive damage -detection of release will vary depending upon the chemical -visual, smell, odor, air monitoring Payment for PPE - CORRECT ANSWERS-must be provided by the employer at no cost to employees, except for specific items such as: -safety toe wear -prescription safety eyewear -everyday clothing and weather related gear Engineering Controls - CORRECT ANSWERS-If......the work environment can be physically changed to prevent employee exposure to the potential hazard, THEN......the hazard can be eliminated with an engineering control Examples: -Initial design specifications -substitute less harmful material -change process -enclose process -isolate process Work Practice Control - CORRECT ANSWERS-IF........employees can change the way they do their jobs and the exposure to materials....THEN...the hazard can be eliminated with a work practice control Examples: Job rotation/wet method/personal hygiene/housekeeping and maintenance Responsibilities - CORRECT ANSWERS-Employer:
