Health HazardsExcerpt from NIOSH Pocket Guide for Methyl demeton:
Hazards Summary · 1 件

It is less toxic than demeton. [ACGIH] A cholinesterase inhibitor that may cause CNS effects; Can be absorbed through skin; [ICSC] The average of two baseline respective cholinesterase activity determinations three days apart, with no exposures to enzyme inhibiting pesticides for at least 30 days, is recommended for each worker prior to exposure to cholinesterase inhibitors because of large inter-individual differences in published baseline values. To be established at least once a year. Removal from workplace exposures is recommended until the cholinesterase activity returns to within 20% of baseline. [TLVs and BEIs]

Reactive GroupEsters, Sulfate Esters, Phosphate Esters, Thiophosphate Esters, and Borate Esters

Reactivity Profile · 1 件

Organothiophosphates, such as METHYL DEMETON, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.

Chemical DangersDecomposes on burning. This produces phosphorous oxides and sulfur oxides.
Flammable LimitsCombustible Liquid
Packaging and LabellingDo not transport with food and feedstuffs.

Fire Fighting · 2 件

Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)

Use water spray, powder, foam, carbon dioxide.

First Aid Measures · 4 件

Fresh air, rest. Refer for medical attention.

Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention .

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention .

First Aid · 2 件

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

(General first aid procedures)

Safe StorageKeep in a well-ventilated room. Separated from food and feedstuffs. Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing.
Exposure Control and Personal Protection · 2 件

Biological Exposure Indices (BEI) [ACGIH] - Acetylcholinesterase activity in red blood cells = 70% of individual's baseline; Butylcholinesterase activity in serum or plasma = 60% of individual's baseline; Sample at end of shift; [TLVs and BEIs]

Nonfire Spill Response · 1 件

SMALL SPILLS AND LEAKAGE: If you should spill this chemical, use absorbent paper to pick up all liquid spill material. Seal the absorbent paper, as well as any of your clothing which may be contaminated, in a vapor-tight plastic bag for eventual disposal. Wash any surfaces you may have contaminated with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.

Spillage Disposal · 1 件

Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.

Isolation and EvacuationExcerpt from ERG Guide 152 [Substances - Toxic (Combustible)]:
Eye PreventionWear face shield or eye protection in combination with breathing protection.
Fire PreventionNO open flames.
Inhalation RiskEvaporation at 20 °C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying.
Skin PreventionProtective clothing. Protective gloves.
