4. FIRST AID MEASURES
INHALATION: If adverse effects occur, remove to uncontaminated area. Give artificial respiration if not
breathing. If breathing is difficult, oxygen should be administered by qualified personnel. Get immediate
medical attention.
SKIN CONTACT: Wash skin with soap and water for at least 15 minutes while removing contaminated
clothing and shoes. Get immediate medical attention. Thoroughly clean and dry contaminated clothing and
shoes before reuse. Destroy contaminated shoes.
EYE CONTACT: Immediately flush eyes with plenty of water for at least 15 minutes. Then get immediate
medical attention.
INGESTION: Contact local poison control center or physician immediately. Never make an unconscious
person vomit or drink fluids. Give large amounts of water or milk. Allow vomiting to occur. When vomiting
occurs, keep head lower than hips to help prevent aspiration. If person is unconscious, turn head to side. Get
medical attention immediately.
NOTE TO PHYSICIAN: For inhalation, consider oxygen. Avoid gastric lavage or emesis.
5. FIRE FIGHTING MEASURES
FIRE AND EXPLOSION HAZARDS: Severe fire hazard. May ignite on contact with water or moist air.
Dust/air mixtures may ignite or explode.
EXTINGUISHING MEDIA: regular dry chemical, dry sand, lime, soda ash
Large fires: Keep unnecessary people away, isolate hazard area and deny entry. Let the fire burn.
FIRE FIGHTING: Do not use water. Do not use foam. Move container from fire area if it can be done
without risk.

AUTOIGNITION: 158 F (70 C)
6. ACCIDENTAL RELEASE MEASURES
SOIL RELEASE:
Dig holding area such as lagoon, pond or pit for containment. Cover with plastic sheet or tarp to minimize
spreading and protect from contact with water.
WATER RELEASE:
Neutralize.
OCCUPATIONAL RELEASE:
Avoid heat, flames, sparks and other sources of ignition. Do not touch spilled material. Stop leak if possible
without personal risk. Do not get water directly on material. Small dry spills: Collect material into suitable,
loosely covered container for disposal. Move containers away from spill to a safe area. Small liquid spills:
Absorb with sand or other non-combustible material. Collect spilled material in appropriate container for
disposal. Large spills: Dike for later disposal. Powder spills: Cover with plastic sheet or tarp to minimize
spreading and protect from contact with water. Keep unnecessary people away, isolate hazard area and deny
entry. Stay upwind and keep out of low areas. Notify Local Emergency Planning Committee and State
Emergency Response Commission for release greater than or equal to RQ (U.S. SARA Section 304). If
release occurs in the U.S. and is reportable under CERCLA Section 103, notify the National Response
Center at (800)424-8802 (USA) or (202)426-2675 (USA).
7. HANDLING AND STORAGE
STORAGE: Store and handle in accordance with all current regulations and standards. Keep separated from
incompatible substances.
8. EXPOSURE CONTROLS, PERSONAL PROTECTION
EXPOSURE LIMITS:
SODIUM METHYLATE:
No occupational exposure limits established.
VENTILATION: Provide local exhaust ventilation system. Ventilation equipment should be explosion-
resistant if explosive concentrations of material are present. Ensure compliance with applicable exposure
limits.
