Maintenance on equipment at an oil and gas facility is an everyday occurrence in Alberta, Canada. Due to their inherent hazards, especially from explosion, fire and chemicals, these facilities (refineries and upgraders) are tightly regulated places in which to work. In these plants, hazards can come in many different shapes and forms; all of which must be mitigated to ensure the safety of both the equipment and the workers. Examples of such hazards include hydrogen sulphide (H2S), naturally occurring radioactive material (NORM), ergonomics and noise.

The intent of this survey was to determine if there were any gaps in Client A’s and Company B’s procedures that result in endangering the workforce. The effectiveness of the mitigations in place for H2S, NORM, ergonomics and noise were all surveyed via gas and vapour survey, NORM Survey, ergonomics survey and noise survey.

The findings suggest that the maintenance company (Company B) has deficiencies in their procedures and that the Client (Client A) has procedures to keep the exposure levels below Alberta Occupational Exposure Limits but still warrants further investigation.
