3M's PanelSafe lockout system mechanically prevents the movement of breaker handles from the OFF position to the ON position with energy-isolating lockout pins. With PanelSafe, 3M is dedicated to helping the customer meet applicable OSHA regulations, which require all electrical circuits to be locked out prior to the servicing and maintenance of machines, lighting, and equipment. The 3M PanelSafe lockout system complies with OSHA standard 1910.147.

The unit, supplied with pre-drilled mounting holes, fastens directly to the service panel dead-front using self-tapping screws. The energy-isolating lockout pins are stored in a holding device also attached to the dead-front by means of self-tapping screws, making the entire assembly and its accessories completely contained behind the panel door. Those authorized to perform a lockout function need only carry their lock and tag.

As a permanently installed circuit breaker lockout system, 3M's PanelSafe is designed with pre-spaced slots that correspond to the center point of the service panel breaker handles. The unit is properly positioned when the center of each pin slot is aligned with the center of each breaker handle. Once installed, 3M PanelSafe, which fits all brands and models, eliminates the need for employees to constantly carry numerous lockout devices each designed to fit a specific manufacturer's panel and breaker type.

For the ultimate flexibility, a standard pin package includes both single-sided and dual-sided pins for simultaneously locking off multiple circuits. Additionally, the package contains a hook pin designed for use in situations where protecting against a nuisance turn-off of dedicated or passive circuits is critical. Such applications may include fire suppression systems, emergency lighting, and computer systems.

3M offers various pins, shims, and brackets so that the PanelSafe lockout system can be used, even if the panel front is not flat. The use of 3M PanelSafe will increase safety, as well as help reduce costs.
