All About Cyanide Hazard

Special Handling of HCL spill incident.

This time I want to discuss and try to share some knowledge about HCL leakage handling in transit.

Before long discussion let us know first what is HCL

MATERIAL SAFETY DATA SHEET
HYDROCHLORIC ACID

1. IDENTITY OF PRODUCTS AND COMPANIES
   PRODUCT NAME: Hydrochloric acid
   CHEMICAL FORM: HCl
   PRODUCTION CODE: -
   SYNONIM: Chloride acid, muriic acid, Hydroge chloride

2. COMPOSITION OF MATERIALS
   Material 36% by weight CAS No.7647-01-0
   Exposure Limits: 5ppm (7.5 mg / m3) (TLV-C)

3. HAZARDS IDENTIFICATION
   Summary of important hazards: Chloride acid is highly corrosive and toxic and irritant when in contact with skin, eyes or inhalation.
   As a result to health:
   EYE: Causing irritation can even lead to blindness
   SKIN: Causes burns and dermatitis
   TABLE: Causes burns of mucous membranes in the mouth, esophagus and mouth
   INHALATION: Causes chronic bronchitis
   Carcinogenic: No effect
   Teratogenic: No effect
   Reproduction: No effect
   

4. FIRST AID ACTION ON ACCIDENTS
   Affected on:
   EYE: Flush with running water for at least 15 minutes
   SKIN: Wash with water as much as possible. Immediately remove contaminated clothing.
   SWITCHING: When conscious, give 1 to 2 glasses for dilution. Avoid artificial sweeteners.
   INHALED: Immediately move the victim to a sufficient place of air, give artificial respiration or oxygen victim immediately take it to the doctor.
   

5. FIRE FIGHTING MEASURES
   a. Properties of combustible substances: Non-combustible
   Flash point : -
   b. The flame temperature itself: -
   c. Flammable area
   Flammability lowest limit: -
   Flammable upper limit: -
   d. Extinguishing media: Applicable with ordinary fire extinguishers. Containers exposed to heat can be sprayed with water to cool, but water should not enter the container.
   e. Special hazards: When contact with metals will produce flammable hydrogen gas
   f. Fire extinguishing instructions: Applicable with ordinary fire extinguishers. Containers exposed to heat can be sprayed with water to cool but water should not enter the container. Wear protective clothing and breathing apparatus.

1. ACTIONS ON SPILL AND LEAKAGE
   a. Small spills and leaks: If leaks are not large, cover with dry soil, dry sand or other unburned material followed by plastic sheets to avoid spreading or contact with rain water.
   b. Large spills and leaks: Gas leak handling or spillage of Hcl solution should wear personal protective equipment, especially breathing apparatus, skin (body)
   c. Personal protective equipment: Chemical absorbent Respirator HCL or air respirator (SCBA), Glasses (goggles) or face shield (full face), gloves (neoprene, nitrile).
   

2. STORAGE AND HANDLING MATERIALS
   a. Material handling: Working with gas or steam HCl should be in a fume hood. Be wary of gas leaks.
   b. Prevention of exposure: Use SCBA and protective clothing
   c. Fire and explosion prevention measures
   d. Storage: Store in a cool, ventilated place and the building floor must be acid-resistant.
   e. Special requirements of material storage: Keep away from oxidizing agents and alkali materials, as well as cyanides, sulfides, formaldehyde, sodium metals, mercury sulfates and ammonium hydroxides. Check for acid leakage.

3. PRELIMINARY CONTROL AND SELF-PROTECTOR EQUIPMENT
   a. Technical control: Use a common Ventilation that covers to keep the dust to the lowest possible level.
   b. Personal protective equipment: Chemical absorbers HCl or air respirators, goggles, Lab coats, full face, neoprene gloves

1. PHYSICAL AND CHEMICAL PROPERTIES
   Shape: Liquid
   Strong scent
   Color: Clear until slightly yellowish
   Mass type: 2.13
   Boiling Point: 85 oC
   Melting point: -20oC
   Vapor pressure (20oC): 20 mbar
   Solubility in Water (20 ° C): dissolved
   82.3 g / 100 m
   pH (20 oC): 1
   
2. REACTIVITY AND STABILITY
   a. Properties of Reactivity: HCl compounds are stable at room temperature. By the influence of heat will break down into hydrogen and chlorine. Solutions in water are highly reactive with metals and produce explosive hydrogen gas. Reacting with the oxidizing agent produces chlorine gas.
   b. Properties of stability: Stable under pressure with normal temperature.
   c. Conditions to avoid: hot and humid
   d. Substances to be avoided: Aluminum, amines, carbide, hydrides, fluorides, alkali metals, metals, strong salts from oxihalogone, concentrated H 2 SO 4, semimetallic hydrogen compounds, semimetalic oxides, aldehyde, sulphides, lithium, silicide, vinymethyl ether
   e. Decomposition material: Hydrochloric acid chlorine
   f. Polymerization Hazards: -
