Specific Guidelines

The compressed gases and cryogenic liquids presented on the following pages are organized in product categories having similar health hazards and storage requirements. These categories are as follows:

Table 1


Nonflammable, Non-corrosive, Low Toxicity.

Store these products in well-ventilated areas or in covered outdoors areas, keeping them off the ground and away from radiant heat sources. Cylinder temperatures should not exceed 125 °F (52 °C).

Note: Nonflammable, Non-corrosive, Low Toxicity products listed in Table 1 can be safely stored together with Toxic and/or Corrosive, Nonflammable products listed in Table 4.

Table 2


Flammable, Non-corrosive, Low Toxicity.

Store these products in well-ventilated areas equipped with electrical equipment in accordance with Article 500 of the National Electrical Code. These products may also be stored in covered outdoor areas, but keep them off the ground and away from radiant heat sources. Keep all ignition sources and combustible materials out of the storage area. Cylinder temperature should not exceed 125 °F (52 °C).

Note: Flammable, Non-corrosive, Low Toxicity products listed in Table 2 can be safely stored together with Flammable, Corrosive, and/or Toxic products listed in
Table 3.

Table 3


Flammable, Corrosive, And/Or Toxic.

Store these products in well-ventilated areas equipped with electrical equipment in accordance with Article 500 of the National Electrical Code. These products may also be stored in covered outdoor areas, but keep them off the ground and away from radiant heat sources. Keep all ignition sources and combustible materials out of the storage area. Cylinder temperature should not exceed 125 °F (52 °C).

Note: Flammable, Corrosive, and/or Toxic products listed in Table 3 can be safely stored together with Flammable, Non-corrosive, Low Toxicity products listed in
Table 2.

Table 4


Toxic And/Or Corrosive, Nonflammable.

Store these products in well-ventilated areas or in covered outdoor areas, but keep them off the ground and away from radiant heat sources. Cylinder temperature should not exceed 125 °F (52 °C).

Note: Nonflammable, Non-corrosive, Low Toxicity products listed in Table 1 can be safely stored together with Toxic and/or Corrosive, Nonflammable products listed in Table 4.

Table 6


Toxic.

These products are very toxic. The slightest exposure to these products can kill. Preferably, store these toxic gases outdoors in a fenced-in area that has been locked and posted. This area must be covered with the cylinders kept off the ground and away from radiant heat sources. If stored indoors, toxic gas cylinders must be kept in well-ventilated areas. Cylinder temperatures should not exceed 125 °F (52 °C).

In addition to being toxic, arsine, diborane, and phosphine are also flammable. The storage area for flammable toxic gases should have electrical equipment conforming to Article 500 of the National Electrical Code. Space all ignition sources and combustible materials out of storage areas.

Warning: Do not store Toxic products with products in any other hazard category.
