CAUTION: Magnesium-based flash powders are more sensitive and violent than those made with aluminum. Individuals inexperienced with flash are encouraged to avoid such compositions.

DANGER: Chlorate and sulfur/sulfide mixes are known to be very sensitive to shock, flame, spark and friction.

DANGER: Chlorate flash mixtures decompose faster than perchlorate flash mixtures and are more sensitive to shock, flame, spark and friction.

DANGER: Chlorate and red phosphorus mixes are extremely sensitive and highly dangerous, and can explode with little provocation. Even experienced individuals are encouraged to avoid such compositions.

CAUTION: Magnesium-based flash powders are more sensitive and violent than those made with aluminum. Individuals inexperienced with flash are encouraged to avoid such compositions.

CAUTION: Calcium metal and calcium hydride react with water exothermically to evolve hydrogen gas. Compositions containing calcium metal or calcium hydride should be sealed against moisture and not be stored.

DANGER: Potassium permanganate mixes are regarded as sensitive and unstable. They should not be stored under any circumstances.

DANGER: Chlorate flash mixtures decompose faster than perchlorate flash mixtures and are more sensitive to shock, flame, spark and friction.

DANGER: Barium peroxide is unstable and prone to spontaneous decomposition. Flash mixtures made with barium peroxide should not be stored under any circumstances, and extreme caution must be exercised when handling such compositions.

CAUTION: Magnesium-based flash powders are more sensitive and violent than those made with aluminum. Individuals inexperienced with flash are encouraged to avoid such compositions.

CAUTION: Magnesium/teflon mixtures have been known to ignite spontaneously, however circumstances surrounding such incidents are not well known. Individuals intending on making such a composition are urged to exercise extreme caution.

DANGER: Chlorate flash mixtures decompose faster than perchlorate flash mixtures and are more sensitive to shock, flame, spark and friction.

DANGER: Barium chlorate is unstable and prone to spontaneous decomposition. Flash mixtures made with barium chlorate should not be stored under any circumstances, and extreme caution must be exercised when handling such compositions.
