CHAS – Contractors Health & Safety Assessment Scheme

CHAS (Contractors Health and Safety Assessment Scheme) is a Government run scheme. Each month thousands of contractors and consultants apply for work with public and private sector organisations. In order to be awarded the relevant contract, the companies and individuals applying must meet health and safety standards.

To avoid each individual contract having to assess individual suppliers health and safety competence, the CHAS Scheme was developed. CHAS provides information and assurances about the health and safety systems and competence of the Organisations who have been CHAS assessed or accredited.

What does CHAS assess?

CHAS assesses Tandem Contracts on our health and safety policy statement, our company and how it deals with health and safety and their specific health and safety arrangements. This means that everyone will work to an acceptable standard.

The CHAS assessment concentrates on the health and safety management and compliance issues that apply to the work Tandem Contracts undertake.

Listed below are the main areas that are assessed by CHAS. Each area must be accompanied by documented evidence and examples of Tandem’s competence.

PASMA is the lead trade association in Europe for the mobile access tower industry. Representing the interests of manufacturers, suppliers, specifiers and users, it provides and oversees the industry standard training scheme and is a major publisher of safety-related knowledge, information and guidance.

Working in collaboration with other trade and professional bodies, industry regulators and key decision makers, PASMA fulfils a number of distinct roles:

  • It provides and governs the industry standard training scheme for mobile access towers. Standard and advanced courses deliver proficiency and competence as required by the Work at Height Regulations. For many, the PASMA certificate and ID card are the only acceptable proof of competence.
  • It is a single, central source of information on all aspects of mobile access towers. DVDs, pocket cards, guidance notes and posters provide a wealth of information, as does the PASMA Code of Practice, the definitive reference for users, their supervisors and managers. Not forgetting the PASMA website:
  • It sponsors research, innovation and best practice. Most, if not all, the training and technical advances in towers and tower use have involved PASMA and its various specialist committees. These are made up of experts who know and understand towers and speak the language.
  • It helps set the standard. The association is an important contributor to the development and enhancement of standards governing the construction, use, inspection and maintenance of mobile access towers – not just nationally but internationally. It also works closely with the Health and Safety Executive (HSE).
  • It plays a major part in promoting mobile access towers for temporary work at height – not just in construction and building maintenance, but in facilities management, the local government sector and retail. Taking part in conferences, seminars and workshops is an essential part of the association’s educational remit.
