INHALATION: move victim to fresh air and call doctor immediately; give mouth-to-mouth resuscitation if needed; keep victim warm and comfortable; oxygen should be given only by experienced person, and only on doctor's instructions.

EYES: flush with large amounts of running water for at least 15 min., holding eyelids apart to insure thorough washing; get medical attention as soon as possible; do not use chemical neutralizers, and avoid oils or ointments unless prescribed by doctor.

SKIN: flush affected area with large amounts of water, do not use chemical neutralizers; get medical attention if irritation persists.

INGESTION: do NOT induce vomiting; have victim drink large amounts of water or milk immediately; if vomiting occurs, give more fluids; get medical attention. (USCG, 1999)

Excerpt from ERG Guide 135 [Substances - Spontaneously Combustible]:

DO NOT USE WATER, CO2 OR FOAM ON MATERIAL ITSELF. Some of these materials may react violently with water. CAUTION: For Xanthates, UN3342 and for Dithionite (Hydrosulfite/Hydrosulphite) UN1384, UN1923 and UN1929, USE FLOODING AMOUNTS OF WATER for SMALL AND LARGE fires to stop the reaction. Smothering will not work for these materials, they do not need air to burn.

SMALL FIRE: Dry chemical, soda ash, lime or DRY sand, EXCEPT for UN1384, UN1923, UN1929 and UN3342.

LARGE FIRE: DRY sand, dry chemical, soda ash or lime EXCEPT for UN1384, UN1923, UN1929 and UN3342, or withdraw from area and let fire burn. CAUTION: UN3342 when flooded with water will continue to evolve flammable Carbon disulfide/Carbon disulphide vapors. If it can be done safely, move undamaged containers away from the area around the fire.

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 or in contact with substance. 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)

DO NOT USE WATER. USE DRY CHEM TO EXTINGUISH FIRE. WHERE ACCESS TO THE AREA IS STRICTLY CONTROLLED, IT MAY BE BEST TO ALLOW THE RELEASE TO BURN SPONTANEOUSLY. FIGHT FIRE FROM PROTECTED LOCATION OR MAXIMUM POSSIBLE DISTANCE.

If material on fire or involved in fire: Do not extinguish fire unless flow can be stopped. Do not use water on material itself. Use graphite, soda ash or powdered sodium chloride. If fire becomes uncontrollable or container is exposed to direct flame-consider evacuation of one-third mile radius.

Excerpt from ERG Guide 135 [Substances - Spontaneously Combustible]:

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: 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)

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

If material not on fire and not involved in fire: Do not use water on material itself. Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Keep material dry. Avoid breathing vapors. Do not handle broken packages without protective equipment. Wash away any material which may have contacted the body with copious amounts of water or soap and water. Approach fire with caution. If material leaking (not on fire) consider evacuation from downwind area based on amount of material spilled, location and weather conditions.

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.

Excerpt from ERG Guide 135 [Substances - Spontaneously Combustible]:

ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. Do not touch or walk through spilled material. Stop leak if you can do it without risk.

SMALL SPILL: CAUTION: For spills of Xanthates, UN3342 and for Dithionite (Hydrosulfite/Hydrosulphite), UN1384, UN1923 and UN1929, dissolve in 5 parts water and collect for proper disposal. CAUTION: UN3342 when flooded with water will continue to evolve flammable Carbon disulfide/Carbon disulphide vapors. 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. (ERG, 2024)

Store in a cool, dry, well-ventilated location. Separate from air, water, oxidizing materials, organic peroxides, flammable materials. Keep material under carbon dioxide, nitrogen, or other inert gas.

User-Reported

DIETHYLZINC is pyrophoric in air, it ignites instantaneously. It reacts explosively with alcohols (methanol, ethanol), bromine, chlorine or liquefied sulfur dioxide [Houben-Weyl, 1973, 13.2a, p. 855, 757, 709]. Reaction with water, nitro compounds, arsenic trichloride, phosphorus trichloride is violent [Bretherick, 5th ed., 1995, p. 587].

Reacts violently with bromine, water, nitro compounds. ... Reacts violently with nonmetal halides (e.g., arsenic trichloride or phosphorus trichloride to produce pyrophoric triethyl arsine or triethyl phosphine).

Reacts violently /with water/ to form flammable ethane gas.

Diethyl zinc and ethyl sodium react with water to produce ethane, a very flammable gas.

Ignition occurs on contact with chlorine.

Anaemia results from the excessive absorption of zinc suppressing copper and iron absorption, most likely through competitive binding of intestinal mucosal cells. Unbalanced levels of copper and zinc binding to Cu,Zn-superoxide dismutase has been linked to amyotrophic lateral sclerosis (ALS). Stomach acid dissolves metallic zinc to give corrosive zinc chloride, which can cause damage to the stomach lining. Metal fume fever is thought to be an immune response to inhaled zinc. (L48, L49, A49)

No indication of carcinogenicity to humans (not listed by IARC).

Chronic exposure to zinc causes anemia, atazia, lethargy, and decreases the level of good cholesterol in the body. It is also believed to cause pancreatic and reproductive damage. (L49)

Inhalation (L49) ; oral (L49) ; dermal (L49)

Ingestion of large doses of zinc causes stomach cramps, nausea, and vomiting. Acute inhalation of large amounts of zinc causes metal fume fever, which is characterized by chills, fever, headache, weakness, dryness of the nose and throat, chest pain, and coughing. Dermal contact with zinc results in skin irritation. (L49)

Dermatotoxin - Skin burns.

Zinc poisoning is treated symptomatically, often by administering fluids such as water or milk, or with gastric lavage. (L49)

INHALATION OF MIST OR VAPOR CAUSES IMMEDIATE IRRITATION OF NOSE & THROAT; EXCESSIVE OR PROLONGED INHALATION OF FUMES FROM IGNITION OR DECOMP MAY CAUSE "METAL FUME FEVER" (SORE THROAT, HEADACHE, FEVER, CHILLS, NAUSEA, VOMITING, MUSCULAR ACHES, PERSPIRATION, CONSTRICTING SENSATION IN LUNG, WEAKNESS ... PROSTRATION) ... SYMPTOMX USUALLY LAST 12-24 HR, WITH COMPLETE RECOVERY IN 24-48 HR. EYES ARE IMMEDIATELY & SEVERELY IRRITATED ON CONTACT WITH LIQ, VAPOR, OR DILUTE SOLUTION; WITHOUT THOROUGH IRRIGATION, CORNEA MAY BE PERMANENTLY DAMAGED. MOISTURE IN SKIN COMBINES WITH CHEMICAL TO CAUSE THERMAL AND ACID BURNS; TISSUE MAY BE SCARRED WITHOUT PROMPT TREATMENT. INGESTION IS UNLIKELY BUT WOULD CAUSE IMMEDIATE BURNS AT SITE OF CONTACT, PAIN, NAUSEA, VOMITING, CRAMPS, AND DIARRHEA MAY FOLLOW; IF UNTREATED, TISSUE MAY BECOME ULCERATED.
