How to Manage Asbestos Exposure Risks Using Permit to Work Procedures

Asbestos — a word that still sends shivers through health and safety professionals worldwide. This once-popular building material, used for its insulation and fireproofing properties, is now known to be one of the deadliest workplace hazards. Prolonged exposure to asbestos fibres can lead to serious diseases like mesothelioma, lung cancer, and asbestosis — illnesses that often remain undetected for years.

In industries like construction, shipbuilding, maintenance, and demolition, managing the risk of asbestos exposure is a critical part of ensuring worker safety. One of the most reliable ways to control these risks is by using a formal Permit to Work (PTW) system.

In this article, we’ll walk you through the dangers of asbestos exposure, why a Permit to Work system is vital, and provide a clear, step-by-step guide on how to manage this hazard effectively.

Before diving deeper, it’s worth mentioning that professionals aiming to improve their safety management skills should consider enrolling in a NEBOSH Course. This globally respected certification equips safety practitioners with in-depth knowledge about hazard control, including asbestos management and the implementation of PTW systems. In fact, many organizations make NEBOSH certification a requirement for those overseeing hazardous jobs.

Why Asbestos Exposure is a Deadly Workplace Hazard

Asbestos becomes dangerous when its tiny fibres are released into the air and inhaled. The problem is — you can’t see, smell, or taste these fibres. Once inhaled, they get trapped in the lungs, causing scarring and long-term health issues that often remain undiagnosed until it’s too late.

Common activities that can disturb asbestos include:

  • Demolishing old buildings

  • Drilling or cutting into walls and ceilings

  • Repairing old insulation or fireproofing materials

  • Sanding or cleaning areas where asbestos dust is present

Without proper control measures, workers and bystanders are at serious risk.

What is a Permit to Work (PTW) System?

A Permit to Work system is a structured, formalized process used to control high-risk jobs. It ensures that tasks like working near asbestos-containing materials (ACMs) are planned, authorized, and completed safely.

The PTW process includes:

  • Identifying potential hazards

  • Defining control measures

  • Assigning competent, trained personnel

  • Monitoring conditions and job progress

  • Ensuring proper record-keeping and permit closure

For asbestos-related work, this system ensures no one stumbles into a hazardous situation without full awareness and protection.

A Real Incident: The Price of Neglect

A few years back, at an old industrial site in Rawalpindi, an unplanned renovation project led to workers unknowingly cutting into walls containing asbestos. No PTW system was in place, and no asbestos survey had been conducted. As a result, several workers inhaled dust containing asbestos fibres.

Months later, two workers were diagnosed with early signs of asbestosis. An investigation revealed that a simple Permit to Work procedure — requiring a material survey before cutting or drilling — could have prevented this exposure.

It’s tragedies like these that underline the importance of a proactive, structured approach.

Key Safety Procedures for Managing Asbestos Exposure Using a Permit to Work

Let’s now break down the essential steps every organization should follow.

Step 1: Conduct an Asbestos Survey and Risk Assessment

Before starting any work that might disturb building materials, an asbestos survey must be conducted. This identifies:

  • Location and condition of asbestos-containing materials (ACMs)

  • Type of asbestos present

  • Potential for fibre release during planned tasks

The findings should be documented and form the basis of the risk assessment, which evaluates the likelihood of exposure and its severity.

Step 2: Apply for a Specific Asbestos Work Permit

The site manager or supervisor should then apply for a dedicated Asbestos Work Permit. This permit outlines:

  • Exact location and nature of the work

  • Results of the asbestos survey

  • Identified hazards

  • Control measures to be implemented

  • Names of authorized and trained personnel

No work should commence without an approved permit.

Step 3: Isolate the Work Area

Once the permit is approved, it’s critical to physically isolate the affected area. This may involve:

  • Erecting warning signs and barriers

  • Sealing off the space with plastic sheeting

  • Closing ventilation systems

  • Establishing decontamination units

Only personnel listed on the permit should be allowed near the area.

Step 4: Provide Suitable Personal Protective Equipment (PPE)

Authorized workers must be equipped with:

  • Disposable overalls

  • Type P3 respirators or full-face masks

  • Gloves and safety boots

  • Eye protection

These controls should be clearly detailed in the Permit to Work document.

Step 5: Ensure Trained and Competent Personnel

Only trained and competent workers should handle or work near asbestos. This is where recognized qualifications like the NEBOSH Course play a crucial role. Trained personnel are better prepared to understand the risks, implement control measures, and react appropriately in emergencies.

Workplace safety experts often recommend that site supervisors managing hazardous jobs complete certified training programs to develop these skills.

Step 6: Implement Air Monitoring

Continuous air monitoring should be conducted before, during, and after the work to detect fibre levels. If airborne asbestos concentrations exceed safe limits, work must stop immediately.

The PTW should specify acceptable air quality levels and monitoring responsibilities.

Step 7: Control Waste Disposal

Any materials contaminated with asbestos must be double-bagged, labeled, and disposed of at approved hazardous waste sites. The permit should detail how and where waste will be managed.

Step 8: Decontaminate Personnel and Equipment

Once the job is complete:

  • Workers should remove PPE in designated decontamination units

  • Tools and equipment should be thoroughly cleaned

  • Air monitoring should confirm that asbestos fibre levels are safe before reopening the area

These final checks should be recorded in the PTW system before closing the permit.

Additional Workplace Safety Tips for Asbestos Management

  • Conduct awareness sessions for all employees

  • Display clear asbestos hazard signage

  • Maintain an asbestos register for older buildings

  • Plan for emergencies, including accidental exposure procedures

  • Schedule periodic medical checkups for at-risk workers

The Value of Safety Training

A strong Permit to Work system is only as effective as the people managing it. That’s why ongoing training is essential.

Many professionals now enroll in the Safety Officer Course in Multan to sharpen their skills in hazard management, asbestos control, and PTW procedures. This type of course builds confidence in applying real-world safety practices and ensures workplaces meet legal and ethical safety standards.

Conclusion

Managing asbestos exposure risks using Permit to Work procedures is a non-negotiable requirement for responsible employers. It’s not about ticking boxes — it’s about saving lives and preserving health.

The Importance of Effective Subcontractor Management in Times of Change

Image
  In any modern workplace — especially in industries like construction, manufacturing, oil and gas, or logistics — subcontractors play a crucial role. Whether you're bringing in specialists for equipment installation, waste disposal, or facility upgrades, their presence often overlaps with your in-house operations. During times of workplace change, this overlap can quickly turn into a risk if subcontractors aren’t properly managed. What makes it tricky is that workplace transitions already create uncertainty. New hazards emerge, old safety plans need adjusting, and processes are in flux. In such situations, subcontractors — who may not be familiar with your company’s updated procedures or hazard controls — can unintentionally increase safety risks. And here’s a point most businesses overlook: proper subcontractor management isn’t about supervision alone; it’s about communication, coordination, and compliance management at every step. For those managing safety on busy or high-risk s...
