1. PSC Safety Range for Handling of Brines
Project Sales Corp is pleased to introduce its product range found
useful in handling high density brines. High density brines have unique
chemical properties and consequently should be handled in a different
manner than conventional muds, especially for safety reasons.
Please feel to circulate this presentation to your colleagues who might
benefit from the use of this.

3. Brines – Exposure to skin
As a general rule, brine solutions become more irritating to the skin as the density of the
fluid is increased and/or the pH of the fluid becomes more acidic. With prolonged
exposure, CaCI2 and CaBr2 can be irritating to the skin and ZnBr2, because of its acidic
nature, can be more irritating to the skin.
If these brines are not washed off and if contaminated clothing is not removed, skin
burns can result. CaCl2 and CaBr2 should be washed off using soap and water within
several minutes, certainly no longer than ten minutes. Remember that these brines will
pull the moisture directly from the skin due to their hygroscopic properties. ZnBr2, due
to its acidic and hygroscopic nature, should be removed from the skin immediately.
Heavy brines immediately irritate the eyes, mucous membranes and any cuts or
scratches that are contaminated. As a general rule, the severity of the irritation increases
with density, i.e. from CaCI2 to CaBr2 to ZnBr2 with ZnBr2 being the most severe.
