Excerpt from ERG Guide 137 [Substances - Water-Reactive - Corrosive]:
When material is not involved in fire, do not use water on material itself.
SMALL FIRE: Dry chemical or CO2. If it can be done safely, move undamaged containers away from the area around the fire.
LARGE FIRE: Flood fire area with large quantities of water, while knocking down vapors with water fog. If insufficient water supply, responders should withdraw.
FIRE INVOLVING TANKS, RAIL TANK CARS OR HIGHWAY TANKS: Cool containers with flooding quantities of water until well after fire is out. Do not get water inside containers. 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)
NO water. In case of fire in the surroundings, use appropriate extinguishing media. In case of fire: keep drums, etc., cool by spraying with water. NO direct contact of the substance with water.
NO hydrous agents. NO water. In case of fire in the surroundings: use appropriate extinguishing media ... Cool drums, etc., by spraying with water but avoid contact of the substance with water.
· 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.
· Do not touch damaged containers or spilled material unless wearing appropriate protective clothing.
· Stop leak if you can do it without risk.
· Use water spray to reduce vapors; do not put water directly on leak, spill area or inside container.
· Keep combustibles (wood, paper, oil, etc.) away from spilled material.
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.
· Prevent entry into waterways, sewers, basements or confined areas.
Excerpt from ERG Guide 137 [Substances - Water-Reactive - Corrosive]:
IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.
SPILL: See ERG Table 1 - Initial Isolation and Protective Action Distances on the UN/NA 1831 datasheet.
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 in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.
· 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.
· 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.
Small spill:
- ISOLATE in all directions: 60 m (200 ft)
Large spill:
- ISOLATE in all directions: 300 m (1000 ft)
- PROTECT people from downwind during DAY time: 0.4 km (0.2 mi)
- PROTECT people from downwind during NIGHT time: 1.0 km (0.6 mi)
- PROTECT people from downwind during DAY time: 2.9 km (1.8 mi)
- PROTECT people from downwind during NIGHT time: 6.3 km (4.0 mi)
Evacuate danger area! Consult an expert! Personal protection: chemical protection suit including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Do NOT absorb in saw-dust or other combustible absorbents. Collect leaking liquid in sealable containers. Absorb remaining liquid in dry sand or inert absorbent. Then store and dispose of according to local regulations. Cautiously neutralize remainder with lime or soda ash.
Evacuate danger area! Consult an expert! Ventilation. NEVER direct water jet on liquid. Do NOT absorb in saw-dust or other combustible absorbents. Collect leaking liquid in covered plastic containers. Absorb remaining liquid in dry sand or inert absorbent and remove to safe place. Do NOT let this chemical enter the environment.
SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.
Solid remedies react with spilled liq to form skin that supresses fumes to permit close approach or completely solidifies spill.
SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal and plant life; and conformance with environmental and public health regulations.
Extremely corrosive. Handle with great care.
SRP: Contaminated protective clothing should be segregated in a manner so that results in no direct personal contact by personnel who handle, dispose of, or clean the clothing. Quality assurance procedures to confirm the efficacy of the cleaning procedures should be implemented prior to the decontaminated protective clothing being returned for reuse by the workers. Contaminated clothing (including shoes/socks) should not be taken home at end of shift, but should remain at employee's place of work for cleaning.
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
