(for non-ambulatory staff and patients- transport down stairs)
Fans will not be used in the lab for everyday temperature
control. Facilities department will be
contacted in situations to provide room temperature
adequate for analyzer operation and staff comfort.
A safe working environment is the goal in prohibiting fans
near bio-safety cabinets, chemical
fume hoods and areas that could generate aerosolization
of pathogens, cause evaporation of reagents and
specimens or interfere with negative pressure that is
required when dealing with infectious agents.

LABORATORY CHEMICAL SAFETY
ROUTES OF EXPOSURE:
RESPIRATORY – Inhalation hazards from chemicals that produce dust, fumes, gases or vapors
require use of face masks, safety glasses or goggles, face shields, chemical fume hoods or biosafety
cabinets.
OCULAR – Wear safety glasses, goggles or use a face shield to protect your eyes from
chemical splashes.

ORAL – Wear a surgical mask or face shield to keep chemical splashes away from your mouth.
No mouth pipetting is allowed – use mechanical pipetting devices only. Wear gloves, wash hands
regularly and don’t put any objects including fingers into your mouth.
CONTACT - To avoid contact with chemicals, guard exposed skin and mucous membranes with
protective clothing and equipment (lab coats, gloves, face shields, face masks, safety glasses or
goggles, fume hoods or biosafety cabinets. Keep lab surfaces clean. When performing procedures
that create droplets or possible spills, clean immediately.
IN CASE OF A CHEMICAL SPLASH OR SPILL RESULTING IN INJURY REQUIRING EMERGENCY
TREATMENT:
IMMEDIATELY WASH AFFECTED AREA WITH A GENEROUS AMOUNT OF WATER.
ON YOURSELF OR YOUR CLOTHING: SHOWER (PULL THE RING ON THE SAFETY
SHOWER FOR RAPID DISCHARGE OF WATER) AND REMOVE CONTAMINATED CLOTHING.
SEEK MEDICAL ATTENTION IF NECESSARY.
IN YOUR EYES: WASH EYES USING THE EYE WASH STATION FOR 15 MINUTES. IF AN
EYE WASH STATION IS NOT AVAILABLE, FLUSH WITH SINGLE-USE PERSONAL EYE WASH
SALINE BOTTLES AND SEEK IMMEDIATE MEDICAL ATTENTION.
ON THE FLOOR: CHECK THE MSDS FOR APPROPRIATE ACTION TO BE TAKEN.
IN CASE OF MINOR SPILLS, USE THE SPILL KIT IN YOUR LABORATORY OR ABSORB THE
SPILL WITH PAPER TOWELS, COVER WITH 10% BLEACH, ABSORB FOR 10 MINUTES AND
DISPOSE MATERIAL INTO BIOHAZARD BAG OR CONTAINER.
REPORT ALL MAJOR SPILLS TO THE SAFETY OFFICER AND COMPLETE A LABORATORY SPILLS
REPORT FORM
Contact time (dwell time) for disinfectants:
Sani-cloth Disposable Cloths:
Purple top (Super Sanicloth) 2-3 minutes
Orange top (bleach) 4 minutes
Grey top (AF3) 3 minutes
Red top(Sanicloth Plus) 3 minutes
