Understanding OSHA §1910.22: Aisles, Stairways, Walkways, and Crawlways in Data Centers

OSHA §1910.22, commonly referred to as the General Industry Walking-Working Surfaces standard, sets the requirements for aisles, stairways, walkways, and crawlways across various industries, including data centers. This regulation ensures that employees can safely navigate their work environments, minimizing the risk of accidents and injuries.

Application to Data Centers

In data centers, where the layout can be dense and complex due to the high concentration of equipment, adherence to §1910.22 is crucial. The standard requires that all aisles, stairways, and walkways be kept clear of obstructions and properly maintained to prevent hazards. This is particularly important in data centers where emergency access and egress routes must remain unobstructed at all times to facilitate quick and safe evacuation.

Key Requirements

• Clearance: Aisles and walkways must have sufficient clearance to allow safe passage. In data centers, this means ensuring that server racks, cables, and other equipment do not encroach on these pathways.
• Non-slip Surfaces: All walking surfaces, including stairs and ramps, must be designed to prevent slipping. This is vital in data centers where spills or condensation from cooling systems could pose a slip hazard.
• Proper Lighting: Adequate lighting is required to ensure visibility of walking surfaces and potential hazards. In data centers, where lighting may be dimmed to conserve energy, special attention must be paid to emergency lighting systems.
• Maintenance: Regular maintenance is essential to keep all walking surfaces in good condition. In data centers, this includes checking for and repairing any damaged flooring or structural elements that could pose a risk.

Practical Implementation

Implementing §1910.22 in data centers involves more than just following the letter of the law. It requires a proactive approach to safety management. For instance, I've seen data centers use color-coded pathways to delineate emergency routes, which not only complies with OSHA's requirements but also enhances overall safety. Additionally, regular safety audits can help identify potential hazards before they become issues. Based on available research, individual results may vary, but these measures have been shown to significantly reduce the risk of accidents in data centers.
