3. HAZARDS IDENTIFICATION
Class Name of Hazardous Chemicals for SDS in Japan: Not applicable
Adverse Human Health Effects:
Effect of over exposure: We have never faced the poisoning problem attributed to
mepronil technical on laboratory researchers, factory workers and users, however,
over-exposure experiments on animals showed that the administration of an extra-ordinary
large quantity of mepronil technical may cause hypoactivity, abnormal walking and
prostration.
4. FIRST AID MEASURES
Skin Contact: -----Wash material off the skin in flowing water or shower with soap. If irritation
persists, consult a physician immediately.
Eye Contact: ------Immediately flush with copious amount of water for at least 15 minutes.
Inhalation: ---------Remove the victim to fresh air and keep him warm and quiet. Get a medical
attention immediately. If not breathing, clear the airway and give artificial
respiration. If breathing is difficult, give oxygen.
Ingestion: ----------Induce vomiting by giving one or two glasses of water. Get a medical
attention immediately. If the victim is unconscious or having convulsions,
never give fluids or induce vomiting.
5. FIRE FIGHTING MEASURES
1/3
MSDS Basitac Technical
Flash Point (Pure active ingredient: 225
Flammability: No data available
Extinguishing Media: Dry chemical powder, foam, carbon dioxide or dry sand
Special Fire Fighting Procedure:
鈥? For small fires, use dry chemical powder, carbon dioxide or dry sand.
鈥? For big fires, foam extinguisher is effective to shut off air. Water may enlarge fire.
鈥? For a fire in surrounding area, apply water to cool and protect surrounding equipments.
Remove containers, if feasible, from the fire area to safe place immediately.
鈥? Fire fighters should wear protective gears including a positive pressure self-contained
breathing apparatus (SCBA). Evacuate non essential personnel.
6. ACCIDENTAL RELEASE MEASURES
鈥? Evacuate non essential personnel by roping an area of leak or spill. Evacuate people to
upwind of the spilled area. Remove all sources of ignition; No flares, smoking, or flames in
the area immediately. Wear protective gears and never work downwind.
鈥? For small spills, adsorb with inert materials (e.g. dry sand or earth), then place in a waste
chemical container for disposal. Flush residual spill (area) with a plenty of water.
鈥? For large spills, dike with sand to lead spill to safe place and then cover with foam. Place in
a waste chemical container as much as possible. Flush residual spill (area) with a plenty of
water. Prevent spills from entering sewers, watercourses or low areas.
7. HANDLING AND STORAGE
Handling Precaution: KEEP OUT OF REACH OF CHILDREN
鈥? Wear appropriate protective gears to avoid breathing dust and contact with skin, eyes or
clothing. Handle the product upwind.
鈥? Keep containers tightly closed or the use of local exhaust is recommended.
鈥? Shut off all gas pilot and electrical (spark or hot wire) igniters and other sources of ignition
during use and until all vapour (odour) are gone.
鈥? Do not expose to friction or shock. Avoid rough handling or dropping.
Storage Precaution:
鈥? All the electrical appliances used in a storage should be installed directly to the ground.
The appliances must be explosion-proof.
鈥? A great quantity of hazardous meterial should be stored in the appropriate storage set up
under the regulation.
鈥? It will coagulate in low temperatures, so careful attention is needed for temperature drop in
winter time.
8. EXPOSURE CONTROL/PERSONAL PROTECTION
Control Parameters:
ACGIH TLV (1992-93) Not established
Engineering Controls:
鈥? The use of local exhaust ventilations is recommended. Containers should be kept tightly
closed.
鈥? Make available emergency showers and eye washes in a work area.
Personal Protective Equipment:
鈥? Wear chemical cartridge respirator with an organic vapour cartridge, safety goggles,
chemical-resistant gloves and boots as appropriate.
