These 11 accidents are divided into two parts: (1) the absence of gas monitoring; and (2) the lack of proper gas testing (“Seven Key,” 2010).
The bulletin mentioned about OSHA’s (Occupational Safety and Health Administration) standard practices that should be critically followed during the work’s operation. The OSHA hot work standard 29 CFR 1910.252 refers to guidelines in performing welding, brazing, and other similar field operations. Usually, OSHA discourages hot work in an environment that is prone to explosion. However, OSHA fails to directly mandate the utilization of combustible gas detector before and during the hot work (“Seven Key,” 2010).
Of the seven lessons drawn, two of these lessons are given emphasis: first is analyzing the hazards; and second is monitoring the atmosphere (“Seven Key,” 2010). To analyze the hazards means conducting assessment in the work field. Workers or technical professions identify the work’s scope, study possible hazards, and look for ways of controlling or eliminating these hazards. On the other hand, to monitor the atmosphere means to check, from time to time, if there’s a presence of flammable gas using the combustible gas detector (“Seven Key,” 2010). Clearly, these lessons offer methods or procedures on how to conduct hot works before those works are carried out.
On the one hand, the bulletin’s premise on the third lesson (i.e., monitoring the atmosphere) is quite heavy, if not redundant. In conducting gas monitoring, says the bulletin, it should be done before and during the hot work operation (“Seven Key,” 2010). I wonder if it can be done only before, no more after, the hot work activity. This has three main implications: (1) the combustible gas detector is unreliable; (2) the technical men employing such detector do not know how to properly use them; (3) there’s no use of monitoring the atmosphere before hot work begins. Moreover, the
