The CSB issues safety recommendations to prevent the recurrence or reduce the likelihood or consequences of similar incidents or hazards in the future. Recommendations are issued to a variety of parties, including government entities, safety organizations, trade unions, trade associations, corporations, emergency response organizations, educational institutions, and public interest groups. Recommendations are published in CSB reports and are closed only by vote of the Board. The CSB tracks all recommendations and communicates regularly with recommendations recipients to ensure that the recommended corrective actions are implemented.

Develop a recommended practice on alarm management specifically for the drilling industry based on guidance in ANSI/ISA 18.2 Management of Alarm Systems for the Process Industries. The recommended practice will address the unique dynamic environment of the drilling industry and provide guidance on implementing a state-based alarm system for different operating modes (e.g., drilling, circulating, tripping, etc.). Include International Association of Drilling Contractors (IADC) in the development of this recommended practice.

2018-01-I-OK-5

Develop a new recommended practice or modify an existing recommended practice (e.g. API RP 54 Recommended Practice for Occupational Safety for Oil and Gas Well Drilling and Servicing Operations) addressing the protection of rig workers on onshore drilling rigs from fire and explosion hazards in the event of a blowout. The recommended practice will specifically address:

(a) Protecting drilling cabin occupants from blowout hazards including heat, blast overpressure, and projectiles, such as requiring an increased fire rating for the driller’s cabin that would allow enough time for occupants to evacuate during a blowout and fire;

(b) Minimum required evacuation methods from the drilling cabin, rig floor, and mast or derrick in the event of a blowout so that personnel can quickly escape in variable hazard location conditions. For example, floor exit hatches and exits on the driller’s cabin wall opposite the rig floor could provide safe evacuation routes during a blowout and fire; and

(c) Proximity of the Blow Out Preventer (BOP) activation controls with the driller.

The above options could be retrofitted on existing drilling rigs. Additionally, formally evaluate alternative locations for the drilling cabin that establishes a safe distance from fire and explosion hazards (e.g., ground level).
