example dioxin
✔✔Macule - ✔✔flat, colored spot on the skin, Freckles, measles
✔✔papule - ✔✔small, solid, raised lesion on surface of the skin; wart, insect bite
✔✔Pustules - ✔✔pus-filled sacs such as those seen in acne, or pimples
✔✔Vesicles - ✔✔Fluid filled blister such as those seen in chicken pox
✔✔Nodules - ✔✔small lumps, lesions, or swellings that are felt when the skin is
palpated; solid mass
✔✔wheal - ✔✔hives
✔✔Tetanus (lockjaw) - ✔✔Clostridium tetani
,Results in tectonic or tonic contractions of the muscles
Incubation: 2 days - 2 months (mostly two weeks)
✔✔Electrical burns cause? - ✔✔Neurologic, vascular and dermal injuries
✔✔Electrical burns travel? - ✔✔Least to most path of resistance; nerve, blood, vessel,
muscles, skin, tendon, fat, bone
✔✔Chemical burns; acidic/alkali - ✔✔Irrigate with copious amounts of water for at least
20 minutes;
Except for dry lime brush first
Neutralizing is obsolete
✔✔Hydrofluoric acid - ✔✔Use calcium gluconate gel and square inject after iced
Zephirin irrigation to stop deep burning
✔✔heat cramps - ✔✔muscle pain and spasm resulting from exposure to heat and
inadequate fluid and salt intake
Treatment: Fluids, electrolytes, cool area
✔✔heat exhaustion - ✔✔Skin cool, clammy and pale: Circulatory collapse from sodium
depletion and ineffective circulating blood volume, the pulse will be weak and
respiratory rapid and shallow

102 or below
Strip clothes, turn on side, expose more skin
60° water spray, cold water lavage is necessary
Maintain airway
✔✔Cold stress - ✔✔Excessive loss of heat that results in increased respirations and
nonshivering thermogenesis to maintain core body temperature
Warm core temperature until > 86°
✔✔Engineering methods - ✔✔Are procedures which may be used to reduce the stress
of a hot environment. Examples include general ventilation, spot cooling, local exhaust,
air conditioning, fan, etc
✔✔Administrative work practice - ✔✔Controls include acclimatize to heat, work-rest
program, rotation of workers, education and training
, ✔✔Critical incident technique - ✔✔Is a method of identifying errors and unsafe
conditions that contribute to both potential and actual injurious accidents within a given
population by means of a stratified random sample of participants and observer
selected from within this population
✔✔Acetylene - ✔✔Is a colorless gas with a slight garlic like older
✔✔A job safety analysis is a technique to? - ✔✔Identify hazards associated with each
step of the job
✔✔The analysis technique where individuals are interviewed about accidents, near
misses, and hazardous conditions is known as which of the following? - ✔✔Critical
incident technique
✔✔Potentiation - ✔✔A substance which does not have a toxic effect upon a system or
organ, but when in combination with another chemical, makes the chemical much more
toxic.
✔✔Methylene chloride is a mild toxic and his primary metabolite is? - ✔✔Carbon
monoxide
✔✔A person can lose his or her heat acclimatization in as little as? - ✔✔3 days

to them
✔✔Viton - ✔✔The type of glove material that offers protection against chlorinated
solvents
✔✔Quantitative fit testing - ✔✔Quantitative fit testing checks for leakage that results in
the employee smelling or sensing the presence of the fit test material.

of__________ Hours of offsite training prior to assignment. - ✔✔40 hours
✔✔The amount of a chemical that kills 50% of the organisms exposed to it in the air is
the: - ✔✔LC50
