Confined Space E&A – Permit Requirements

A permit-required confined space has one or more of these characteristics:

• Contains any other recognized serious safety or health hazards.
• Contains or has the potential to contain a hazardous atmosphere;
• Contains a material with the potential to engulf someone who enters the space;
• Has an internal configuration that might cause an entrant to be trapped or asphyxiated by inwardly converging walls or by a floor that slopes downward and tapers to a smaller cross section

OSHA’s Confined Space Standard

OSHA'nın kapalı alanlara ilişkin standardı (29 CFR 1910.146), genel endüstride çalışanları izin verilen alanlara girmenin tehlikelerinden korumak için uygulama ve prosedürlere ilişkin gereklilikleri içerir.

Employers in general industry must evaluate their workplaces to determine if spaces are permit spaces. If a workplace

contains permit spaces, the employer must inform exposed employees of their existence, location and the hazards they pose. This can be done by posting danger signs such as “DANGER — PERMIT-REQUIRED CONFINED SPACE — AUTHORIZED ENTRANTS ONLY” or using an equally effective means.

Çalışanların izin alanlarına girmemesi ve buralarda çalışmaması gerekiyorsa, işverenler bu alanlara girmelerini önlemek için etkili önlemler almalıdır. Çalışanların izin alanlarına girmesi bekleniyorsa, işveren yazılı bir izin alanı programı geliştirmeli ve bunu çalışanlara veya temsilcilerine sunmalıdır.

Alternative to a full permit entry

Under certain conditions described in the standard, the employer may use alternate procedures for worker entry into a permit space. For example, if an employer can demonstrate with monitoring and inspection data that the only hazard is an actual or potential hazardous atmosphere that can be made safe for entry using continuous forced air ventilation, the employer may be exempted from some requirements, such as permits and attendants. However, even in these circumstances, the employer must test the internal atmosphere of the space for oxygen content, flammable gases and vapors, and the potential for toxic air contaminants before any employee enters it. The employer must also provide continuous ventilation and verify that the required measurements are performed before entry.
