During one inspection, MMA investigators observed a wireline operator using a cellphone on a mobile offshore drilling unit during active wireline operations. This use violated facility safety procedures and resulted in an incident of non-compliance.
In another inspection, MMA observed portable electronic devices not rated for hazardous locations in a Class 1, Division 2 hazardous area, with no hot work permit issued.
MMA emphasizes the importance of not using cell phones and other portable electronic devices during active operations unless their use is authorized and controlled. Portable electronic devices  not properly rated for hazardous locations can create ignition hazards and should not end up used without proper safeguards.
Therefore, MMA recommends operators and contractors consider the following:
- Prohibit portable electronic device use in hazardous areas unless devices end up certified as intrinsically safe for the applicable class and division.
- Reinforce adherence to portable electronic device policies during facility orientations, and prior to safety-critical operations.
- Require Hot Work Permits when portable electronic device use remains unavoidable in hazardous areas, consistent with API RP 14F (§12.3 and §12.9) and API 500.
- Review company policies for portable electronic device usage and ensure they comply with 30 CFR 250.114 and API 14F standards.
- Ensure offshore installation managers and company representatives understand hazardous area classification, portable electronic device ignition hazards, and proper installation and operating permit requirements.
