Lockout Hasps

Lockout Hasps are the backbone of group lockout procedures. They let multiple workers secure the same isolation point with individual padlocks so a circuit or machine cannot be restarted until every technician removes their own lock. These are built for jobsite abuse with steel, aluminum, or non conductive nylon and finishes that hold up to oil, moisture, and daily handling.

Used across manufacturing, utilities, and heavy construction, Lockout Hasps are a simple tool that delivers reliable OSHA 1910.147 compliance during team maintenance.

Built for Team Safety

Every hasp is designed so crews can add personal locks to a single isolation point. The jaws pass through breaker lockouts, valve handles, and switch hasps. When the last worker removes their lock, the system can be re energized. That is how you enforce true group control in the field.

Industrial Grade Construction

Choose the material that matches your environment and procedure.

Steel Hasps

Maximum strength and tamper resistance for heavy equipment and mechanical isolation. Powder coated for visibility and corrosion control.

Aluminum Hasps

Lightweight and corrosion resistant for humid or outdoor areas. Easy to handle with gloves and ideal for frequent use.

Non Conductive Hasps

Reinforced nylon bodies that prevent current transfer. The choice for electrical lockouts and tight clearances where arcing risk is present.

Common Applications

• Electrical panel isolation
• Valve and machine maintenance
• Group energy control on shared systems
• Plant wide shutdowns and utilities work

Subcategories

Aluminum Lockout Hasps

Corrosion resistant and easy to handle. Favored in food processing, marine, and outdoor utility environments.

Steel Lockout Hasps

Built for maximum durability and abuse resistance. Common in machine shops, fabrication, and heavy industrial maintenance.

Non Conductive Lockout Hasps

Dielectric protection for electrical work. Reinforced nylon resists impact and prevents current transfer.

Double End Hasps

Two jaw sizes on one tool. Crews can lock small switch points and larger valve handles without changing tools.

Why Lockout Hasps Matter for Compliance

Group lockouts require every worker to control their own lock. Hasps make that physical rule impossible to bypass. Supervisors can verify at a glance that all positions are locked, and color coding helps track which departments have cleared maintenance before restart. This is the simple hardware that prevents accidental energization on team jobs.

Frequently Asked Questions

What exactly does a Lockout Hasp do in a team procedure

It lets each technician place a personal lock on the same isolation point. The equipment stays de energized until every lock is removed which satisfies OSHA group control rules.

How many locks can a single hasp hold

Standard hasps hold six locks. Extended bodies hold up to twelve. That covers most multi trade maintenance teams on a single isolation point.

Are aluminum hasps acceptable for electrical work

Aluminum conducts. Use non conductive nylon for electrical isolation or any area where arcing or contact risk exists.

When should I use a double end hasp

Use double end hasps when you move between mixed devices. One jaw fits small breaker devices and switch hasps. The other jaw fits larger valve handles. It saves time and reduces gear swaps.

Do you offer spark proof options

Yes. Brass and aluminum spark resistant models are available for flammable atmospheres in oil and gas or chemical processing.

Will these fit through valve lockouts and breaker devices

Yes. Jaw diameters match the holes on common breaker lockouts, valve covers, and switch plates so one hasp can secure many device ty

How long do hasps last in daily use

Steel and aluminum hasps regularly serve five to ten years with normal wear. Nylon bodies last similar timelines if kept away from sharp edges and high heat.

Can I standardize colors across the plant

Yes. Many sites use red for electrical, blue for mechanical, and yellow for pneumatic. We can match your color plan and engrave numbers for inventory control.
