Catalyst handling procedures to minimize exposures

Report no. 95/57: This report outlines a generalized approach to reducing worker exposure to solid and liquid catalysts during refinery catalyst handling activities such as reactor loading, unloading and screening. Many catalyst handling operations have the potential for generating airborne dust, mist or vapour, depending on the nature of the catalyst involved, and due care and attention is necessary to prevent adverse health effects.

The report stresses that engineering controls should be adopted as the primary means of minimizing exposures, although it acknowledges that the use of personal protective equipment,such as respirators, goggles and gloves, is also necessary in many catalyst handling activities.
