Delivering consistency of health and safety standards in the construction industry.

Measuring Health and Safety

CHASNZ has made these simple but effective tools available for free use across the NewZealand construction sector. They can be used to gain an independent view as to how health and safety is perceived by the workforce and used as tools to pinpoint risk areas and drive improvement. 
Why Safety Climate? Organisational safety climate has been defined as employee perceptions regarding organisational policies, practices and procedures that signal the value and importance of safety within the workplace (Neal, Griffin, & Hart, 2000). Safety climate has been shown to be a strong predictor of workplace accidents and conditions associated with health and safety performance (Probst et al., 2019)

Whakatipu (Data Lake)

Using data to provide insight and action is not a new management science. In many other fields, such as banking, insurance, fraud detection and customer channel marketing, the use of predictive analytics is commonplace. However, in the field of health and safety, we have lagged! Typically organisations and regulators have relied on descriptive analytics such as injury rate trends and simply grouping similar injury types into categories. Albeit, tools we have used to describe what has happened have become more sophisticated, we have evolved from excel graphs to tools such as Power BI.

Guide to Site Access Requirements

This is a collaborative document and has been produced to provide guidance. The aim is to achieve consistent site access standards and safer workplaces for everyone.

Construction sites have known significant hazards associated with them and Under section 36 of the Health and Safety at Work Act 2015, organisations are to provide any information, training, instruction or supervision that is necessary to protect all persons from risks to their health and safety arising from work carried out.

Knowing that people entering our worksites have been trained as well as knowing their competency level are important and basic steps in carrying out an organisation’s duties under the Health and Safety at Work Act.

This guideline has been written to assist all parties who own, control, visit and or work on construction sites.

Tōtika (Pre-Qualification)

Supplier Health & Safety (H&S) pre-qualification is a tool that supports procurement processes in New Zealand. Currently there are no common standards prequalification resulting in a proliferation of proprietary pre-qualification schemes. This creates significant inefficiency in the supply chain as suppliers have to repeatedly prequalify against different schemes and standards, which causes a continual drain, and wasted time and money for both suppliers and buyers.
