Benzyldimethylamine: Does not have an individual approval but may be used under an appropriate group standard

The New Jersey Worker and Community Right to Know Act requires public and private employers to provide information about hazardous substances at their workplaces. (N.J.S.A. 34:5A-1 et. seq.)

Special Hazards of Combustion Products: Toxic vapors are generated when heated. (USCG, 1999)

· Flammable/combustible material.；· May be ignited by heat, sparks or flames.；· Vapors may form explosive mixtures with air.；· Vapors may travel to source of ignition and flash back.；· Most vapors are heavier than air. They will spread along the ground and collect in low or confined areas (sewers, basements, tanks, etc.).；· Vapor explosion hazard indoors, outdoors or in sewers.；· Those substances designated with a (P) may polymerize explosively when heated or involved in a fire.；· Runoff to sewer may create fire or explosion hazard.；· Containers may explode when heated.；· Many liquids will float on water.

Flammable. Gives off irritating or toxic fumes (or gases) in a fire. Above 57 °C explosive vapour/air mixtures may be formed.

Inhalation may be fatal as a result of spasm, inflammation and edema of the larynx and bronchi, chemical pneumonitis, and pulmonary edema. Symptoms of exposure may include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomitting. (USCG, 1999)

· May cause toxic effects if inhaled or ingested.；· Contact with substance may cause severe burns to skin and eyes.；· Fire will produce irritating, corrosive and/or toxic gases.；· Vapors may cause dizziness or asphyxiation, especially when in closed or confined areas.；· Runoff from fire control or dilution water may cause environmental contamination.

BENZYLDIMETHYLAMINE neutralizes acids on exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. May attack some plastics (USCG, 1999).

Excerpt from ERG Guide 132 [Flammable Liquids - Corrosive]:；Some of these materials may react violently with water.；SMALL FIRE: Dry chemical, CO2, water spray or alcohol-resistant foam.；LARGE FIRE: Water spray, fog or alcohol-resistant foam. If it can be done safely, move undamaged containers away from the area around the fire. Dike runoff from fire control for later disposal. Do not get water inside containers.；FIRE INVOLVING TANKS, RAIL TANK CARS OR HIGHWAY TANKS: Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks in direct contact with flames. For massive fire, use unmanned master stream devices or monitor nozzles; if this is impossible, withdraw from area and let fire burn. (ERG, 2024)

Use water spray, powder, alcohol-resistant foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.

Remove contaminated clothes. Rinse skin with plenty of water or shower. 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. Do NOT induce vomiting. Refer for medical attention .

· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.；· Keep unauthorized personnel away.；· Stay upwind, uphill and/or upstream.；· Ventilate closed spaces before entering, but only if properly trained and equipped.

· ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area.；· All equipment used when handling the product must be grounded.；· Do not touch or walk through spilled material.；· Stop leak if you can do it without risk.；· Prevent entry into waterways, sewers, basements or confined areas.；· A vapor-suppressing foam may be used to reduce vapors.；· Absorb with earth, sand or other non-combustible material.；· For hydrazine, absorb with DRY sand or inert absorbent (vermiculite or absorbent pads).；· Use clean, non-sparking tools to collect absorbed material.；Large Spill；· Dike far ahead of liquid spill for later disposal.；· Water spray may reduce vapor, but may not prevent ignition in closed spaces.

INHALATION: Remove victim to fresh air and call a physician at once; administer oxygen until physician arrives.；INGESTION: Get medical attention at once.；EYES or SKIN: Flush with plenty of water for at least 15 min; if cyanosis is present, shower with soap and warm water, with special attention to scalp and finger nails; remove any contaminated clothing. (USCG, 1999)

General First Aid:；· Call 911 or emergency medical service.；· Ensure that medical personnel are aware of the material(s) involved, take precautions to protect themselves and avoid contamination.；· Move victim to fresh air if it can be done safely.；· Administer oxygen if breathing is difficult.；· If victim is not breathing:；-- DO NOT perform mouth-to-mouth resuscitation; the victim may have ingested or inhaled the substance.；-- If equipped and pulse detected, wash face and mouth, then give artificial respiration using a proper respiratory medical device (bag-valve mask, pocket mask equipped with a one-way valve or other device).；-- If no pulse detected or no respiratory medical device available, provide continuous compressions. Conduct a pulse check every two minutes or monitor for any signs of spontaneous respirations.；· Remove and isolate contaminated clothing and shoes.；· For minor skin contact, avoid spreading material on unaffected skin.；· In case of contact with substance, remove immediately by flushing skin or eyes with running water for at least 20 minutes.；· For severe burns, immediate medical attention is required.；· Effects of exposure (inhalation, ingestion, or skin contact) to substance may be delayed.；· Keep victim calm and warm.；· Keep victim under observation.；· For further assistance, contact your local Poison Control Center.；· Note: Basic Life Support (BLS) and Advanced Life Support (ALS) should be done by trained professionals.；Specific First Aid:；· For corrosives, in case of contact, immediately flush skin or eyes with running water for at least 30 minutes. Additional flushing may be required.

· Wear positive pressure self-contained breathing apparatus (SCBA).；· Wear chemical protective clothing that is specifically recommended by the manufacturer when there is NO RISK OF FIRE.；· Structural firefighters' protective clothing provides thermal protection but only limited chemical protection.

Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Collect leaking and spilled liquid in sealable containers as far as possible. Cautiously neutralize remainder. Then wash away with plenty of water.

Excerpt from ERG Guide 132 [Flammable Liquids - Corrosive]:；IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area for at least 50 meters (150 feet) in all directions.；SPILL: Increase the immediate precautionary measure distance, in the downwind direction, as necessary.；FIRE: If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2024)

Immediate precautionary measure；· Isolate spill or leak area for at least 50 meters (150 feet) in all directions.；Spill；· For highlighted materials: see Table 1 - Initial Isolation and Protective Action Distances.；· For non-highlighted materials: increase the immediate precautionary measure distance, in the downwind direction, as necessary.；Fire；· If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions.
