CHEM121 LAB EXAM
what does the letters in RAMP stand for
R=Recognize hazards
A=Assess risks
M=Minimize risks
P=Prepare for emergencies
Personal factors
attitude, beliefs, personality, skills
behavior factors
safe and risky practices
Environmental factors
location, equipment, procedures
many accidents in labs are cause by
poor house keeping
fire alarms should be pulled when?
when there is a need to leave the building whether there is
a fire or not.
What should you do after pulling the fire alarm
call 911
when leaving during an emergency you should
leave through the nearest exit
if a terrorist attack happen what should you do
hide in a safe place and wait for the emergency personal
what are volatile chemicals
liquids that vaporized at normal temp and pressure
the atmospheric lab pressure
should be negative in relation to the hallway
what is ACH
, air changes per hour
the ACH value for a lab is
dependent on the chemical hood sashes. the higher the
sashes the more air movement
what is the most exposure to chemicals
dermal exposure, the skin
mists
tiny droplets of liquid in the air
dusts
sold particles in the air
fumes
small solid or liquid particles that are formed when a solid
is vaporized
A heterogenous mixture
the contamination is a colloid can be gas, soil, liquid
mixture.
highest risk level of combination of parameters to
lowest
1. high hazard and high probability of exposure
2. high hard and low probity of exposure
3. low hazard and high probably of exposure
4. low hazard and low probably of exposure
risk assessment words highest to low
catastrophic, deadly, serious, significant
what eye protection is acceptable in chemistry labs
chemical splash goggles
the ANSI Z87.1 ensures that eyewear protects against
the impact of shrapnel
when using gloves you should
use the proper technique for removing the gloves to avoid
skin contamination
