miscellaneous

Appearance: White, granular or crystalline solid with a faint, almond-like odor.

Appearance: white granular powder or crystals

Applications: Extraction of gold and silver from ores, as an analytical reagent

Stability: Stable. Incompatible with a variety of materials, includingacids, iodine, peroxides, permanganates, alkaloids, chloral hydrate,metallic salts. Light and moisture sensitive. Contact with acidgenerates extremely toxic HCN gas.

Toxicity: ORL-RAT LD50 10 mg kg-1
Safety: DANGER: POISON, causes cyanosis; skin, eye, lung irritation
Safety: DANGER: POISON, causes cyanosis; skin, eye, lung irritation

Safety: Gloves, safety glasses and good ventilation. Do not usein the open laboratory. Ensure all containers are properly labelled. Keep cyanide poison kit on hand.

First Aid: Eye: Irrigate immediately Skin: Soap wash immediately Breathing: Respiratory support Swallow: Medical attention immediately

Exposure Routes: inhalation, skin absorption, ingestion, skin and/or eye contact

Symptoms: Irritation eyes, skin, upper respiratory system; asphyxia; lassitude (weakness, exhaustion), headache, confusion; nausea, vomiting; increased respiratory rate, slow gasping respiration; thyroid, blood changes

Target Organs: Eyes, skin, respiratory system, cardiovascular system, central nervous system, thyroid, blood

Incompatibilities and Reactivities: Strong oxidizers (such as acids, acid salts, chlorates & nitrates) [Note: Absorbs moisture from the air forming a syrup.]

Personal protection and Sanitation: Skin: Prevent skin contact Eyes: Prevent eye contact Wash skin: When contaminated Remove: When wet or contaminated Change: Daily Provide: Eyewash, Quick drench

Exposure Limits: NIOSH REL*: C 5 mg/m 3 (4.7 ppm) [10-minute] [*Note: The REL also applies to other cyanides (as CN) except Hydrogen cyanide.] OSHA PEL*: TWA 5 mg/m 3 [*Note: The PEL also applies to other cyanide s (as CN) except Hydrogen cyanide.]
