Health Hazard
Excerpt from NIOSH Pocket Guide for Propylene glycol dinitrate:

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

Symptoms: Irritation eyes; conjunctivitis; methemoglobinemia; headache, impaired balance, visual disturbance; In Animals: liver, kidney damage

Target Organs: Eyes, central nervous system, blood, liver, kidneys (NIOSH, 2023)
Reactivity Profile
PROPYLENE GLYCOL DINITRATE is explosive. Acts as a strong oxidizing agent. Heating may cause a violent combustion or explosion producing toxic fumes (nitrogen oxides). May also decompose explosively from shock, friction or from a build-up of electrostatic charge that sparks suddenly to ground. Can begin a vigorous reaction that culminates in an explosion if mixed with reducing agents including hydrides, sulfides, and nitrides and numerous ordinary combustible materials. Reacts violently with Al, BP, cyanides, esters, PN2H, P, NaCN, SnCl2, sodium hypophosphite, and thiocyanates. Reacts with acids and with alkalis, including ammonia and amines. Must be stored in a cool, ventilated place, away from acute fire hazards and easily oxidized materials.

First Aid
Excerpt from NIOSH Pocket Guide for Propylene glycol dinitrate:

Eye: IRRIGATE IMMEDIATELY - If this chemical contacts the eyes, immediately wash (irrigate) the eyes with large amounts of water, occasionally lifting the lower and upper lids. Get medical attention immediately.

Skin: SOAP WASH - If this chemical contacts the skin, wash the contaminated skin with soap and water.

Breathing: RESPIRATORY SUPPORT - If a person breathes large amounts of this chemical, move the exposed person to fresh air at once. If breathing has stopped, perform artificial respiration. Keep the affected person warm and at rest. Get medical attention as soon as possible.

Swallow: MEDICAL ATTENTION IMMEDIATELY - If this chemical has been swallowed, get medical attention immediately. (NIOSH, 2023)
