Lead and behavioural measurement
Published in Tim Marsh, A Definitive Guide to Behavioural Safety, 2017
Regardless, three broad sets can be identified: Operations such as risk assessment, compliance, corrective action closeout, change management and training.Systems would include permit to work, surveys, disciplinary issues and hazard analysis.Behaviour, our primary focus here, including leadership, front-line engagement, ‘walk-and-talk’ and other ‘visible’ methodologies.
Biological safety considerations

Entry to higher hazard areas by maintenance staff is only allowed under a ‘permit to work’ system. The permit is issued to the maintenance staff by the unit manager when the area has been suitably decontaminated and is safe to enter. The permit must be signed by the person who carried out the decontamination when this is not the unit manager, and work must not recommence until the permit is signed off (to indicate that maintenance work is complete).

PS education covered in university is deemed to be less in depth [7]. In real operations, it requires a lot of detail to explore many technical options before choosing a solution [8]. Thus, it is desirable to equip students with the skill/ability to solve problems of cost-effectiveness, safety and time. Shallcross [9] expressed that all CE students should be made aware of where to find information on safety rules, regulations and standards, employer and employee rights and responsibilities following their practising law, record keeping and reporting requirements, permit-to-work systems relating to procedures, fire prevention and protection, hazards of dealing with chemicals, toxic material and hazardous wastes (incl. biomedical hazards), hazards identification and risk minimization methods, hazards associated with maintenance procedures and recovering from process upsets, hazards related to reactive systems, safety management systems, site emergency response (e.g., hazardous material emergencies), environmental protection requirements, process control, human factors and their influence on safety, and inherently safe design.

While a permit to work (PTW) is an important component of a healthy work environment and can aid in the proper management of a variety of tasks, it is subject to human error. Responsible individuals should evaluate work procedures and check safety at all stages of the work, according to COMAH Regulations 2015 with the PTW framework [17]. Permits are also an important means of contact between site managers, plant supervisors and operators, as well as the people who do the job. When the workers sign the permit, this shows that they are aware of the hazards and have taken the necessary precautions. This PTW device may be required for high-risk tasks such as hot work, confined space entry, maintenance operations, the transport of hazardous materials and electrical or mechanical isolations. Research by Hosseini et al. [18] elucidates the most widely recognized assessment of factors leading to human error in the process of PTW issuance and found a strong association between errors and the individuals involved in work permit issuance preparation, work experience and age. Human error, according to Kletz [19], is characterized as any incorrect decision or behaviour that has a negative impact on the efficacy, protection or efficiency of a system.
Empirical investigation into underground utility strikes for supporting incident prevention: cases in Melbourne, Australia

All ground penetration requires a permit before work can commence in Melbourne, Australia. GIS drawings need to be attached to the permit and utility owner maps need to be cross-checked throughout the DBYD process. The GIS drawings provide a map of underground assets across the project. Having GIS or DBYD correctly display the locations of services is an important step. Then, another critical task is having the location of utilities marked out on site. Correct markings on site are valuable for work crews and an essential step for ensuring strikes are avoided. They are commonly made using traditional surveying methods, such as a total station. Finally, the project and some asset owners require positive verification of services prior to digging within certain proximities. Verification is often done using vacuum excavation or handtools.
