Health Hazards of Chemicals
HAZARDOUS AREA CLASSIFICATION PART 4
FREE - Training Module on PERMIT TO WORK
Exposure to Eye
Chemical exposure to eyes is one of
the serious concern in chemical health hazard. If a chemical comes in contact with
the eyes, avoid rubbing but immediately and thoroughly wash the eyes with
flowing water in the nearest eye wash fountain – SPEED IS ESSENTIAL. Ensure the
water coming out of the eye wash is clear and in normal temperature. Have someone dial and summon emergency help. Continue washing for
15 minutes or until the ambulance arrives. It is not good practice to
wear contact lenses in the laboratory. Always ensure the eye protection
while handling or working with any chemicals.
Exposure to Skin
A judicious laboratory practice is to avoid ALL
skin contact with any chemicals. If skin exposure occurs,
wash the entire exposed skin area thoroughly with water – SPEED IS
ESSENTIAL. Ensure the water coming out of the eye wash is clear and in normal
temperature. For
some small area exposures,
a sink outlet may be the closest water source and completely suitable to wash the area, however,
do not hesitate to use the nearest safety shower(ensure water in
normal temperature) if the exposure area cannot be completely covered by
water from a sink outlet. Always ensure
the required personal protective equipment’s while handling or working with any
chemicals.
Inhalation Exposure
Be fully aware of the chemical
properties, read the safety data sheets before handling/working with the
chemicals. Work in
a chemical fume hood to lessen inhalation of potential vapors and dust. If illness from inhalation of a
chemical occurs remove the person at once to fresh air, keep quiet and
warm. Dial the emergency contact number to call an ambulance. If breathing has stopped, begin
artificial respiration at once. Since most chemical fume hoods vent
above the roof, be aware of and inform the Safety Coordinator or Administrator
if toxic or noxious
chemicals may be released. Do not endanger people working outside the
building or on the roof by hood activities.
Exposure by Ingestion
Always ensure the required personal protective equipment’s while handling or working with any chemicals. Thoroughly Wash hands before eating. Do not use laboratory glassware & devices for eating or drinking. These precautions are especially important for anyone working with highly toxic chemicals, microorganisms, parasites or radioactive materials.
