Chemical Hazards Flashcards
When conducting a health exam, the OHN nurse learns that a worker has developed adult asthma that the worker believes is due to an occupational exposure. Which of these chemicals would be considered a possible causative factor for the asthma?
Toluene, an isocyanate is a respiratory sensitizer that can lead to occupational asthma.
An OHN is working in an automotive plant where contract welders have been brought on site to install a new duct system. To evaluate whether the company is meeting OSHA regulations, the OHN should observe the welding process to be sure that:
OSHA regulations 29 CFR 1910 state that fire watchers are required whenever welding is performed in locations where other than a minor fire may develop. In this scenario, sparks or hot slag may fall onto combustible material or be carried through ducts to other locations.
A worker was injured during a chemical spill. The worker was issued gloves during the clean-up operation. In addition to the gloves, the worker should have also used:
To prevent skin and eye irritation, workers should wear gloves, goggles, and face shields. With adequate ventilation and concentrations below recommended exposure levels, respirators are not required.
