Handle lightly; storeroom ventilated, away from open flames, high temperature, sunlight; stored separately from oxidants, flammable materials, food materials

High heat, vibration, impact, friction can be explosive

Unstable. Violently explosive in the concentrated or pure states. Readily forms explosive compounds with heavy metals. This is a dangerous and hard to handle substance which must not be prepared or handled by non-experts.

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.|May be destroyed by converting hydrazoic acid to sodium azide and the reaction mixture decomposed with nitrous acid.

Reacts with heavy metals to form very unstable heavy metal azides. Reacts violently with /cadmium, copper, nickel, nitric acid, fluorine/.|Forms explosive salts with carbon disulfide.

Wear protective gloves and clothing to prevent any reasonable probability of skin contact ... Wear splash-proof chemical goggles and faceshield unless full facepiece respiratory protection is worn.|Where there is potential for exposure to the chemical, use a NIOSH/MSHA approved supplied-air respirator with a full facepiece operated in the positive pressure mode or with a full facepiece, hood, or helmet in the continuous flow mode, or use a NIOSH/MSHA approved self-contained breathing apparatus with a full facepiece operated in pressure-demand or other positive pressure mode.

Dangerously explosive material.

A dangerously sensitive explosive hazard when shocked or exposed to heat.

Containers may explode in fire. Storage containers and parts of containers may rocket great distances, in many directions. If material or contaminated runoff enters waterways, notify downstream users or potentially contaminated waters. Notify local health and fire officials and pollution control agencies. From a secure, explosion-proof location use water spray to cool exposed containers. If cooling streams are ineffective (venting sound increases in volume and pitch, tank discolors or shows any signs of deforming), withdraw immediately to a secure position ... The only respirators recommended for fire fighting are self-contained breathing apparatuses that have full facepieces and are operated in a pressure-demand or other positive-pressure mode.

Evacuate and restrict persons not wearing protective equipment from area of spill or leak until clean-up is complete. Remove all ignition sources. Ventilate area of spill or leak. Absorb liquids in vermiculite, dry sand, earth, peat, carbon, or a similar material and deposit in sealed containers. Keep the chemical out of a confined space, such as a sewer, becau
