Lockout Hasps

Lockout hasps vary by design and material to suit specific industrial needs:​
Standard Aluminum Hasps: Lightweight, corrosion - resistant, and suitable for general industrial use. Ideal for non - electrical environments where moderate strength is required.​
Non - Conductive Hasps: Made from high - impact polypropylene or nylon, these eliminate electrical conductivity risks, making them essential for electrical panel lockout or applications near live circuits.​
Heavy - Duty Steel Hasps: Built for harsh environments (e.g., chemical plants, offshore rigs), offering maximum durability and resistance to extreme temperatures, moisture, and mechanical stress.​
Adjustable Jaw Hasps: Feature expandable/contractible jaws to fit irregularly shaped equipment, such as large valve handles or odd - sized switches, ensuring versatile compatibility.

Selecting the correct hasp involves assessing three key factors:​
Environment & Hazards:​
Use non - conductive hasps for electrical work to avoid shock risks.​
Opt for stainless steel or coated hasps in wet, salty, or corrosive environments.​
Equipment Compatibility:​
Measure the diameter of handles/switches and check the hasp’s jaw opening width and slot spacing to ensure a secure fit.​
For multi - worker lockouts, choose hasps with enough padlock slots (e.g., 2 - 10+ slots depending on team size).​
Compliance Standards:​
Verify certification to OSHA, ANSI, or ISO 45001 to ensure legal and safety compliance.

Lockout hasps are essential across industries to secure energy sources:​
Manufacturing: On conveyor belts, presses, and assembly lines during maintenance.​
Utilities: For circuit breakers, transformers, and electrical panels in power plants or substations.​
Chemicals & Petrochemicals: On valves, pumps, and reactors to prevent accidental startup during shutdowns.​
Construction: On heavy machinery (e.g., excavators, cranes) to lock out ignition switches or control panels.​
Facilities Management: For HVAC systems, boilers, or water pumps during servicing.

Installation follows these simple steps:​
Isolate Energy: Turn off equipment and disconnect power/fluid sources per LOTO procedures.​
Position the Hasp: Align the hasp over the target mechanism (e.g., a switch handle or valve wheel).​
Secure the Hasp: Use the built - in clamp, screws, or straps to fasten it firmly to the equipment.​
Add Padlocks: Insert each worker’s padlock through the hasp slots, ensuring all locks engage fully.​
Tag the Hasp: Attach a lockout tag with the worker’s name, date, and reason for lockout.

Regular maintenance ensures reliability and safety:​
Inspect Monthly: Check for cracks, corrosion, or loose parts—replace damaged hasps immediately.​
Clean Debris: Wipe down non - conductive hasps with a dry cloth; use mild detergent for metal hasps (avoid abrasive tools).​
Lubricate Moving Parts: Apply silicone spray to adjustable jaws or sliding components to prevent sticking.​
Store Properly: Keep hasps in dry, dust - free areas away from direct sunlight to extend material lifespan.

Yes, when used correctly. OSHA’s LOTO standard (1910.147) requires that lockout devices:​
Be standardized in color, shape, or size for easy identification.​
Prevent accidental removal until all authorized workers remove their padlocks.​
Have multiple lock slots for group lockouts.Always choose hasps labeled with OSHA - compliant or ANSI Z244.1 certification to meet regulatory requirements.

Absolutely—they complement other safety equipment:​
Valve Lockouts: Use a hasp to secure a valve lock’s handle when multiple workers need access.​
Circuit Breaker Locks: Attach a hasp to a breaker lock to accommodate team padlocks during shared lockouts.​
Cable Lockouts: Combine with cable hasps for securing large - scale machinery with dispersed energy sources.This versatility makes them a core component of any comprehensive LOTO program.

Purchase from reputable industrial safety suppliers:​
Online Retailers: Platforms like Grainger, SafetyGlobe, or Amazon offer wide selections with customer reviews.​
Specialized Distributors: Companies like Brady, Master Lock, or Duralabel focus on LOTO solutions, ensuring certified products.​
Direct from Manufacturers: For bulk orders or custom designs (e.g., branded hasps for enterprise fleets).

Prices range from
​
10to50+ depending on:​
Material: Non - conductive or steel hasps are pricier than basic aluminum models.​
Features: Hasps with more padlock slots (e.g., 6 - slot vs. 2 - slot) or adjustable jaws cost more.​
Brand & Certification: Premium brands with OSHA/ANSI compliance may have higher price points. Buying in bulk often qualifies for discounts, making them cost - effective for industrial fleets.
