1.         Under what circumstances do I need to implement the PTW system for WAH?

A PTW is required for WAH where a person could fall from a height of more than 3 metres,including falling into depths. Such work activities are deemed as hazardous WAH under the Regulations. Under the WSH (WAH) (Amendment) Regulations 2014 which came into effect from 1 May 2014, the PTW regulatory requirements apply only to workplaces defined as Factories where hazardous WAH is carried out.


2.         Who is the party responsible for ensuring the effective implementation of PTW system for hazardous WAH? Can the PTW system be implemented through external third-party personnel?

The Occupier of the Factory is required to ensure the PTW system is implemented for hazardous WAH in accordance with the Regulations.  The Occupier of the Factory may implement PTW system for hazardous WAH through a third party, other than his own employees (e.g. appoint personnel of contractor as WAH Safety Assessor or Authorised Manager). However, the Occupier still holds the overall statutory duties for implementation of the PTW for hazardous WAH as prescribed under the Regulations. The Occupier cannot delegate his statutory duties to the third party by contractual arrangements


3.         What is the role of WAH Supervisor, WAH Safety Assessor and WAH Authorised Manager?


4.         Can the WAH Safety Assessor and WAH Authorise Manager be the same person?

MOM has made amendments to PTW requirements under the WSH (WAH) (Amendment)Regulations 2014 where the requirement for the WAH Safety Assessor and Authorised Manager to be separate persons has been removed. This refinement was carried out in response to feedback received from Small Medium Enterprises (SMEs) on their operational constraints when implementing the PTW as required under the Regulations.


In principle, the Authorised Manager and the WAH Safety Assessor should where possible, be a separate and dedicated competent person.However, in the event of valid operational and manpower constraints, such as smaller SMEs typically involving small number of personnel during work deployment, a single person may perform concurrent roles of WAH Assessor as well as Authorised Manager, as long as the said person has sufficient experience and training, and able to perform the duties of a WAH Safety Assessor as well as an Authorised Manager under the Regulations.


5.         Can the WAH Supervisor also assume the role of the WAH Safety Assessor?

With regards to the PTW Applicant (i.e. Supervisor of the workers who will carry out the WAH activity), he should NOT concurrently perform the role of a WAH Safety Assessor for the same PTW. The suitability and adequacy of the control measures put in place by the Applicant should be assessed by an independent competent person (WAH Safety Assessor), to ensure the effectiveness and overall integrity of the PTW system and avoid any conflict of interest that may arise.


6.         I have completed and passed WAH Course for Manager, can I also be the WAH Safety Assessor?

No, a person who completed WAH Course for Managers can only be appointed as WAH Authorised Manager.  To be WAH Safet Assessor, he will need to attend WAH Course for Assessor or he is already a registered WSHO


7.         What is the different between WAH course for Assessor/Managers and WAH course for Assessor/Managers (Integrated)?

The two integrated courses are for people who do not have certificates for WAH Course for Supervisors.  It is a direct entry, where it combines the topics covers under WAH Course for Supervisors into WAH Course for Assessors/Managers, thus, reducing the course duration significantly. 


8.         My workers have Building Construction Supervisor Safety Course (BCSS) / Shipyard Safety Supervisors Course (SSSC), do they still need to attend the WAH Course for Supervisors?

WAH Course for Supervisors is specifically designed to allow participants to understand the various requirements, example Fall Prevention Plan & WAH Permit-To-Work (PTW) system, under the WSH (WAH) Regulations 2013 which came into effective on 1st May 2013.


It also consist of practical lesson when it  teaches the participants on the inspection of the Fall Protection Equipment; and the proper donning of the body harness and using the various fall arrest system. 


All the above-mentioned topics are not taught in BCSS/SSSC.  Thus, it will be beneficial for your worker to attend the WAH course for Supervisors.


9.         What is a Fall Prevention Plan (FFP)?

FFP is a site-specific plan prepared by a competent person*  for the purpose of reducing or eliminating the risk of falls by ensuring that all reasonable fall prevention measures and methods have been implemented, prior to the commencement of WAH work.

*  “Competent person” means a person who has sufficient experience and training to perform the work required to be carried out, and has passed such courses as the Commissioner for Workplace Safety and Health may require for that work.


10.       When must the FPP be ready?

Like Risk Assessment (RA) documents, FPP must be ready, available and communicate to the affect parties prior to the commencement of Work-At-Heights activities.
