A hazardous material is any item or agent (biological, chemical, radiological, and / or physical) that has the ability to cause harm to humans, animals, property and/or the environment

Context

Hazardous materials and substances are both used and encountered very frequently in the construction industry such as adhesives, cements, cleaning products, paints and lubricants.

The hazards associated with hazardous materials and substances vary depending on their characteristics, and can be associated with their storage, transportation and handling or usage.

The risks can include:

− Chemical burns

− Respiratory disease

− Impaired vision or blindness, and

− Fire, explosion or chemical reactions

Process
Step 1 Pre-construction planning

The risks arising from hazardous materials are to be identified, assessed and controlled in the Baseline Project Risk Register, in accordance with the hierarchy of controls.

All information relating to existing hazardous materials and substances should be requested to allow for risk assessment and planning

Provision for Hazmat surveying and testing where information does not exist and risk may be present

Third party hygienist required for testing and air monitoring

Regulator notifications

Step 2 Contractor Requirements

All Hazmat contractors must identify all High Risk activities within their scope of work, evidence of experience carrying out these activities, provision for full time supervisor, relevant licenses and competencies of supervisor and workers

All Hazmat contractors are required to develop and submit a removal plan relevant to the hazardous material present

Provide regulator notifications where required

Clearance certification to be provided by qualified person

Specific safe system of work, e.g. SWMS, for this High Risk activity to the Baseline site representative for approval (7days) prior to commencing works

This MUST include an Emergency Procedure / Rescue Plan, evidence that supervisors and workers are trained in the procedure

The Baseline expectation is that our contractors will follow all safety requirements listed within our standards

Note: Evidence of specific licence and associated health monitoring requirements e.g. Asbestos removal A&B, lead paint and industry induction MUST be provided

Step 3 Pre-activity review

Hazmat registers, surveys and testing records to be provided and reviewed prior to commencing works

Hazardous material removal control plans must be reviewed an approved prior to commencing work

Regulator notification confirmed

Proposed methodology to be reviewed by Project Team and assess for need to conduct activity specific High Risk Workshop

(If required) High Risk Workshop to be conducted with contractor undertaking activity and Baseline Project Team

Methodology, competencies and timing MUST be confirmed and agreed with all stakeholders

Step 4 Work activity approval

Prior to commencing Hazmat works in the space a removal control plan must be submitted by the licenced contractor and approved by the Baseline site manager

Exclusion zone, restricted area with signage in place and decontamination area set up

Air monitors set up where required

A toolbox talk must be conducted by a Baseline Project Team member immediately prior to commencing works, and include all workers involved in the activity and emergency response procedure

Step 5 Work activity monitoring

Baseline site manager / supervisor MUST monitor the Hazmat removal activity (from outside the restricted area) until the work activity has been completed.

A Task Observation should be conducted by a Baseline Project Team member to record the works being carried out as per approved SWMS

The Subcontractor Supervisor must be present at all times to ensure the SWMS and permit is being adhered to

Continual air monitoring records to be provided to Baseline and workers to ensure levels are compliant

Daily prestart communications to Hazmat workers via hazmat supervisor for continual awareness of risks

PPE observations to maintain controls

Step 6 Completion of work activity

At the end of the activity the subcontractor hazmat supervisor must confirm the hazmat has been fully removed/encapsulated, area has been vacated by all team members

A qualified hygienist must provide a clearance certificate to confirm area is safe to enter for other workers

The Baseline site manager / supervisor must confirm the clearance certificate has been reviewed and area has been made safe

Controls
Elimination Physically remove the hazard

  • Leave hazmat in place, do not disturb, encapsulate via remote means

  • A clearance certificate is to be obtained prior to workers entering any area where hazardous materials have been removed under the project

Substitution Replace the hazard
  • The hazards associated with substances shall be considered as part of their selection (e.g. using nonflammable paints or adhesives).

Isolation Isolate people from the hazard
  • Erect fully sealed enclosures to separate hazmat removal work from work area

  • Seal hazmat to leave in place or prior to removal

  • Barriers, exclusion zones, signage and / or traffic management is to be in place where work with hazardous substances or materials can impact other persons and / or the environment

  • Hazardous substances / dangerous goods are to be stored in a segregated cabinet or area inline with the associated Safety Data Sheet (SDS), with appropriate signage, ventilation, drainage, containment and / or bunding

Engineering Replace the hazard
  • Use of HEPA filtered H-class industrial vacuum cleaners to remove hazmat dusts and debris

  • Spray equipment includes wet sprays with water mist or wetting solution. A constant low- pressure water supply is required for wetting down asbestos and related items to suppress airborne asbestos fibers

  • Soak the asbestos until total saturation is achieved prior to removal

  • An appropriate class and sized spill kit is to be on-site when quantities of hazardous substances are being stored or used

  • When working with hazardous materials all tools and equipment should be used in conjunction with attachments or mechanisms for encapsulation, capture or suppression of air-borne fibers

  • Equipment used for monitoring purpose (e.g. gas monitors) are to have records of calibration check before use

Administration Change the way people work
  • All personnel using or interacting with hazardous materials or substances must be provided information, training and supervision

  • Emergency management plans shall consider the specific hazmat, its associated hazards and procedure required to control it and affected workers

  • Hazmat removal contractors (e.g. Asbestos removalists) must be appropriately licenced

  • Health monitoring shall be undertaken when workers’ health is at risk following possible exposure.

  • Current Safety Data Sheets (SDS) are to be obtained for all hazardous substances used or stored on site

  • Hazardous waste disposal records are to be retained on site throughout the project

PPE Protect the worker with PPE
  • All PPE used for the removal of asbestos should be inspected before the commencement of the asbestos removal work, after it undergoes any repairs and at least once every seven days when it is continually being used

  • A register with the details of these inspections, the state of the equipment and any repair details should be maintained

  • At the end of the asbestos removal work and upon leaving the asbestos removal work area you must ensure that all PPE is disposed of as asbestos waste

  • PPE should be thoroughly wet before being placed in bags
