HEALTH & SAFETY INFORMATION
• Criteria Document
: NIOSH 78-173 KETONES
•
Vapors cause severe irritation of eyes and throat and can cause eye and lung
injury. They cannot be tolerated even at low concentrations. Liquid causes
severe skin irritant. Causes second and third degree burns on short contact
and is very injurious to the eyes. Permanent damage may occur.
Exposure Limits:
•
ACGIH TLV: 0.2 ppm/1.5 mg/m3, ceiling limit
•
OSHA PEL: None
•
NIOSH REL: 0.2 ppm/1.5 mg/m3 ceiling limit
•
DFG: MEKP (40%) has a very severe effect on skin.
Respirator:
At
any concentrations above the NIOSH REL, or where there is no REL, at any
detectable concentration:
SCBAF:PD,PP
(any self-contained breathing apparatus that has a full facepiece and is
operated in a pressure-demand or other positivepressure mode) SAF:PD,PP:ASCBA
(any suppliedair respirator that has a full facepiece and is operated in a
pressure-demand or other positive-pressure mode in combination with an
auxiliary self-contained breathing apparatus operated in a pressure-demand or
other positive-pressure mode).
Escape:
GMFOV
[any airpurifying, full-facepiece respirator (gas mask) with a chin-style,
front- or back-mounted organic vapor canister] SCBAE (any appropriate
escape-type, selfcontained
breathing
apparatus).
Reactivity:
Forms explosive mixture with
air. Explosive decomposition above 176°F/80°C. Pure substance is
shock-sensitive. Strong oxidizer. Violent reaction with strong acids, strong
bases, reducing agents, combustible substances, organic materials, oxides of
heavy metals, salts, trace contaminants, and amines. May accumulate static
electrical charges; may cause ignition of its vapors.
FIRE INFORMATION:
If material or contaminated runoff enters waterways, notify
downstream users of potentially contaminated water. Flash Point: 125–200°F
(52–93°C) (oc); 180°F (82°C) (cc) (60% MEKP).
FIRST AID:
Move
victim to fresh air. Call emergency medical care. Apply artificial respiration
if victim is not breathing. Administer oxygen if breathing is difficult. Remove
and isolate contaminated clothing and shoes. Remove material from skin
immediately. In case of contact with substance, immediately flush skin or eyes
with running water for at least 20 minutes. Keep victim warm and quiet. Ensure
that medical personnel are aware of the material(s) involved, and take
precautions to protect themselves.
