Fire Hazards · 2 件

Excerpt from ERG Guide 156 [Substances - Toxic and/or Corrosive (Combustible / Water-Sensitive)]:;Combustible material: may burn but does not ignite readily. Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Most vapors are heavier than air. They will spread along the ground and collect in low or confined areas (sewers, basements, tanks, etc.). Vapors may travel to source of ignition and flash back. Corrosives in contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water. (ERG, 2024)

Health Hazards · 2 件

Excerpt from ERG Guide 156 [Substances - Toxic and/or Corrosive (Combustible / Water-Sensitive)]:;TOXIC and/or CORROSIVE; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Contact with molten substance may cause severe burns to skin and eyes. Reaction with water or moist air may release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause environmental contamination. (ERG, 2024)

Excerpt from ERG Guide 156 [Substances - Toxic and/or Corrosive (Combustible / Water-Sensitive)]:;Note: Most foams will react with the material and release corrosive/toxic gases. CAUTION: For Acetyl bromide (UN1716), use CO2 or dry chemical only.;SMALL FIRE: CO2, dry chemical, dry sand, alcohol-resistant foam.;LARGE FIRE: Water spray, fog or alcohol-resistant foam. FOR CHLOROSILANES, DO NOT USE WATER; use alcohol-resistant foam. If it can be done safely, move undamaged containers away from the area around the fire. Avoid aiming straight or solid streams directly onto the product.;FIRE INVOLVING TANKS, RAIL TANK CARS OR HIGHWAY TANKS: Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. Do not get water inside containers. 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. (ERG, 2024)

Accidental Release Measures · 2 件

· 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 damaged containers or spilled material unless wearing appropriate protective clothing.;· Stop leak if you can do it without risk.;· A vapor-suppressing foam may be used to reduce vapors.;· FOR CHLOROSILANES, use alcohol-resistant foam to reduce vapors.;· DO NOT GET WATER on spilled substance or inside containers.;· Use water spray to reduce vapors or divert vapor cloud drift. Avoid allowing water runoff to contact spilled material.;· Prevent entry into waterways, sewers, basements or confined areas.;Small Spill;· Cover with DRY earth, DRY sand or other non-combustible material followed with plastic sheet to minimize spreading or contact with rain.;· Use clean, non-sparking tools to collect material and place it into loosely covered plastic containers for later disposal.

First Aid · 2 件

Excerpt from ERG Guide 156 [Substances - Toxic and/or Corrosive (Combustible / Water-Sensitive)]:;Refer to the "General First Aid" section.

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.

Exposure Control and Personal Protection · 2 件

· 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.

TIH (Toxic Inhalation Hazard) - Term used to describe gases and volatile liquids that are toxic when inhaled. Some are TIH materials themselves, e.g., chlorine, and some release TIH gases when spilled in water, e.g., chlorosilanes. [ERG 2016].
