Inhaling

Exposition to LPG in high concentration in the air could lead to weakness, dizziness, loss of consciousness and ceasing of breathing.
The alkanes (propane and butane) are comparatively strong narcotics, but their impact on the human organism is weakened due to their low solvency in blood. In normal conditions, they are practically harmless.

The toxic impact of propane-butane is exhibited only in cases of high concentration in the air, as it significantly decreases the oxygen content in the inhaled air and could lead to suffocation, loss of consciousness and death.

On account of this reason, propane-butane is classified as asphyxiant.

In concentrations of more than 10%, propane-butane could cause irritation of the respiratory pathways, difficult breathing, dizziness, sleepiness, headache and disorientation. Inhaling of LPG in gas phase should be avoided. When it is in high concentration in the air, it supplants oxygen, as this could be the situation in cases of large spills in close spaces. Entering of such closed areas is absolutely forbidden until examination and permission by a certified official.

In cases of persons, victims of the described situation, the first necessary action is to be moved out at clean air. In cases of ceased breathing, take on artificial respiration and heart massage, if necessary. Call First Aid immediately!

The highest permissible concentration of propane-butane in the air at the working area is 1800 mg/cubic meter, according Regulation №13/1992.

Skin and eyes

In cases of spilling of LPG in liquid phase onto the skin or into the eyes, a cold burning could be provoked as a result of the fast evaporation and taking away of heat from the skin.
In cases of cold burns, pour excessively water over the damaged place to normalize the temperature and cover it with sterile gauze. Immediately call for specialized medical assistance.
