Hazardous Substance Consultancy

The Health and Safety at Work (Hazardous Substances) Regulations [HSW-HS] came into effect on 1 December 2017.  These regulations replace the previous Hazardous Substances and New Organisms (HSNO) Act and supporting Regulations.   

The 2017 regulations include a range of compliance criteria beyond 'straight forward' location or handler certification.  Chemsafety has the expertise to guide you through a potential minefield.

Our Hazardous Substance Management Services include:

  • Location Compliance Certification
  • Certified Handler Certification
  • Certified Handler training
  • HSW-HS compliance requirements assessment
  • Laboratory management systems
  • Tracked substance management systems


Chemsafety has five Compliance Certifiers on staff.  Chemsafety can certify:

  • Location Compliance Certification classes 2 – 5, 6 and 8
  • Certified Handlers Class 6.1A and B
    (excluding vertebrate toxic agents)
  • Some Stationary Container Systems

Do you require a Location Certificate or Certified Handlers??

Perhaps not. Our site assessment identifies the type and volume of hazardous substances that you have on site. We compare these to the threshold amounts (and any exemptions) and determine if certification is required. Our report provides you with a timetable for implementation of the regulatory requirements for your substances (Location Certificates, Certified Handler approvals, Tracking requirements, and compliance with the new regulatory controls).

Laboratory Management / Tracking

Chemsafety can assist with determining if your site laboratory can be managed under Part 18 of the regulations.  We can determine tracking requirements and set up a system for you.   

Hazardous Substance Management Report

Regardless of the quantity of hazardous substances you hold, and whether or not you require certification, you must store hazardous substances correctly in accordance with the Regulations.  We provide reports detailing specific requirements for segregation of incompatibles, hazardous atmosphere zones, signage and documentation, emergency planning, secondary containment, PPE, etc. Our report lists specific regulatory controls relevant to your workplace, determines whether or not you comply, and advise actions required to achieve compliance. These reports are often used as a first step toward achieving Location Certification standard.
