Hazard Class or Division:
3 (FLAMMABLE LIQUID)
ERG Guide:
128
RTECS No:
DE3030000;
SE7555000 (petroleum spirits)
Properties:
Naphthas
derived from both petroleum and coal tar are included in this group. Extremely
flammable watery liquid. Colorless to pale yellow. Gasoline-like odor. Only
0.04% will dissolve; the rest will float on water. Toxic gases such as carbon
monoxide may be produced in fires. Boils between 95°F (35°C) and 140°F (60°C).
Vapors are heavier than air; will collect in low areas.
Uses:
Industrial
solvent.
HEALTH & SAFETY INFORMATION
• IDLH:
1000
ppm [10% LEL]
•
OSHA Table Z-1 Air Contaminant (8030-30-6)
•
Vapors cause smarting of the eyes or respiratory system if present in high
concentrations. High levels of exposure causes drowsiness and loss of
consciousness. Inhalation has resulted in weakness and numbness of the arms
and legs, tremors and loss of muscle control. Symptoms may disappear within a
few months if exposure stops. These symptoms have been attributed to hexane
component. Swallowing the liquid may aspirate into the lungs causing chemical
pneumonia. Chronic exposure causes defatting of the skin, drying and cracking.
Benzene, also a component, has been linked to blood disorders in humans
including leukemia. Percutaneous absorption of liquid is important in
development
of systemic effects if benzene is present.
Exposure Limits:

Respirator:

ppm:
SA:CF (any supplied-air
respirator operated in a continuous-flow mode) CCRFOV [any chemical cartridge
respirator with a full facepiece and organic vapor cartrodge(s)] GMFOV [any
air-purifying, full-facepiece respirator (gas mask) with a chin-style, front-
or back-mounted organic vapor canister] PAPROV [any powered, air-purifying
respirator with organic vapor cartridge(s)] SCBAF (any self-contained breathing
apparatus with a full facepiece) SAF (any supplied-air respirator with a full
facepiece).
Emergency
or Planned Entry into Unknown Concentrations or IDLH Conditions
SCBAF:PD,PP (any self-contained breathing
apparatus that has a full facepiece and is operated in a pressuredemand or
other positive-pressure mode) SAF:PD,PP:ASCBA (any supplied-air respirator that
has a full facepiece and is operated in a pressuredemand 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).
Note:
Substance causes eye irritation or damage;
eye protection needed.
Reactivity:
Naphthas
must be stored to avoid contact with strong oxidizers (such as chlorine,
bromine, and fluorine) since violent reactions occur. Before entering confined
space where these chemicals may be present, check to make sure that an
explosive concentration does not exist. Store in tightly closed containers in a
cool, well-ventilated area away from heat. Sources of ignition such as smoking and
open flames are prohibited where naphthas are handled, used, or stored. Metal
containers involving the transfer of 5 gallons or more of naphthas should be
grounded and bonded. Drums must be equipped with self-closing valves, pressure
vacuum bungs, and flame arresters. Use only non-sparking tools and equipment,
especially when opening and closing containers of naphtha. Wherever naphtha is
used, handled, manufactured, or stored, use explosion-proof electrical
equipment and fittings. Attacks some plastics, rubber, and coatings.

FIRST AID:
Move
victim to fresh air. Call emergency medical care. Apply artificial respiration
if victim is not breathing. If breathing is difficult, give oxygen. Remove and
isolate contaminated clothing and shoes. In case of contact with substance,
immediately flush skin or eyes with running water for at least 20 minutes. Wash
skin with soap and water. Keep victim warm and quiet. Ensure that medical
personnel are aware of the material(s) involved, and take precautions to
protect themselves.
