7.	HEALTH EFFECTS AND FIRST AID

INHALATION:
BENZOIC ACID:
  ACUTE EXPOSURE- Dust may cause mild respiratory irritation with sore throat
    and coughing.
  CHRONIC EXPOSURE- No data available.

FIRST AID- Remove from exposure area to fresh air immediately. If breathing
  has stopped, perform artificial respiration. Keep person warm and at rest.
  Treat symptomatically and supportively. Get medical attention immediately.

SKIN CONTACT:
BENZOIC ACID:
  ACUTE EXPOSURE- Dust and liquid may cause mild irritation and redness.
    Concentrations up to 0.2%, may elicit an immediate skin reaction varying
    from erythema to a non-immunologic contact urticaria in some persons.
  CHRONIC EXPOSURE- Repeated application to human skin produced moderate
    irritation.

FIRST AID- Remove contaminated clothing and shoes immediately. Wash affected
  area with soap or mild detergent and large amounts of water until no
  evidence of chemical remains (approximately 15-20 minutes). Get medical
  attention immediately.

EYE CONTACT:
BENZOIC ACID:
IRRITANT.
  ACUTE EXPOSURE- Dust may cause strong irritation and redness.
  CHRONIC EXPOSURE- Repeated or prolonged contact with irritants may cause
    conjunctivitis.

FIRST AID- Wash eyes immediately with large amounts of water or normal saline,
  occasionally lifting upper and lower lids, until no evidence of chemical
  remains (approximately 15-20 minutes). Get medical attention immediately.

INGESTION:
BENZOIC ACID:
  ACUTE EXPOSURE- Large doses may cause sore throat, gastric pain, nausea,
    vomiting, and possible allergic reactions. A 67 kg man ingested 50 gm
    without ill effects.
  CHRONIC EXPOSURE- A daily intake of 4-6 grams produced no toxic effects
    outside of gastric irritation. Larger doses may have systemic effects
    similar to salicylates and may include disturbances in acid base balance,
    tremor and convulsions.

FIRST AID- Treat symptomatically and supportively. Get medical attention
  immediately. If vomiting occurs, keep head lower than hips to prevent
  aspiration.

ANTIDOTE:
No specific antidote. Treat symptomatically and supportively.

------------------------------------------------------------------------------
7.  REACTIVITY

REACTIVITY:
Stable under normal temperatures and pressures.

INCOMPATIBILITIES:
BENZOIC ACID:
  OXIDIZERS (STRONG): Vigorous exothermic reaction.

DECOMPOSITION:
Thermal decomposition products may include toxic oxides of carbon.

POLYMERIZATION:
Hazardous polymerization has not been reported to occur under normal
temperatures and pressures.

8.    STORAGE AND DISPOSAL

Observe all federal, state and local regulations when storing or disposing
of this substance.


                                 **Storage**

Store away from incompatible substances.

------------------------------------------------------------------------------
9.    CONDITIONS TO AVOID

May burn but does not ignite readily. Avoid contact with strong oxidizers,
excessive heat, sparks, or open flame.

------------------------------------------------------------------------------
10.  SPILL AND LEAK PROCEDURES

SOIL SPILL:
Dig holding area such as lagoon, pond or pit for containment.

Use protective cover such as a plastic sheet to prevent material from
dissolving in fire extinguishing water or rain.

WATER SPILL:
Use activated carbon to absorb spilled substance that is dissolved.

Use mechanical dredges or lifts to extract immobilized masses of pollution and
precipitates.

Use suction hoses to remove trapped spill material.

OCCUPATIONAL SPILL:
Sweep up and place in suitable clean, dry containers for reclamation or later
disposal. Do not flush spilled material into sewer. Keep unnecessary people
away.

Reportable Quantity (RQ): 5000 pounds
The Superfund Amendments and Reauthorization Act (SARA) Section 304 requires

  the working limits of the respirator and must be jointly approved by the
  National Institute for Occupational Safety and Health and the Mine Safety
  and Health Administration (NIOSH-MSHA).
