The WSH Council in Singapore has excellent information about confined spaces

WSH Council shares this information on Working Safely in Confined Spaces

Learn about the hazards of working in confined spaces. Find out about the requirements of the confined space entry permit and the roles of the employer.

 

Hazards in Confined Spaces

Many hazards can exist in confined spaces. Some examples include:

  • Suffocation (due to oxygen deficiency)

  • Fire and explosion (by flammable gases and vapours)

  • Poisoning (by toxic gases, vapours or fumes)

  • Engulfment or entrapment (by materials such as collapsing particles)

  • Falling from heights (openings, scaffolds)

 

Confined Space Entry Permit

The confined space entry permit provides a formal check to ensure that all the elements of a safe system of work are in place before persons can enter and work in confined spaces.

It should include:

  • Identification and location of the confined space;

  • Purpose of entry;

  • Entry date, time and duration;

  • Potential hazards and their control measures;

  • PPE;

  • Other precautions (e.g. barricades, signboards);

  • Emergency response plan;

  • Name of confined space attendant;

  • Atmospheric testing results (of the confined space); and

  • Names and signatures of supervisor, confined space safety assessor and authorised manager.

Employer’s Role

You must:

  • Evaluate the need to enter the confined space.

  • Ensure safe means of access to and egress from the confined space.

  • Make information of the confined space available to persons who may be exposed to the hazards of the confined space.

  • Ensure safe practices are in place for opening the entrance to the confined space.

  • Ensure there is sufficient and suitable lighting for entry into and work in the confined space.

  • Implement procedures and controls for entry into the confined space including gas testing.

  • Provide training for working safely in confined spaces for workers and supervisors.

  • Establish emergency rescue plan and provide rescue equipment.

  • Appoint a confined space attendant.

You should also consider sending your workers who are involved in confined works to attend the SSG WSQ Perform Work in Confined Space Operation (PWICSO)

 

This PWICSO course was formerly called Safety Orientation Course for Workers - Manhole SOCManhole or Manhole SOC

The SSG WSQ Perform Work in Confined Space Operation (PWICSO) is one of the core units in all process sectors of Process Industry.

People who should attend PWICSO are

  • Confined Space Entrant (includes manholes, tanks, vessels, etc)

  • Confined Space Attendant (includes manholes, tanks, vessels etc)

 

PWICSO Assumed Skills and Knowledge

PWICSO Learners will be able to listen, read, speak and write English at a proficiency level equivalent to the Employability Skills System (ESS) Level 2.

Course Outline for Perform Work in Confined Space Operations

for the SSG WSQ Perform Work in Confined Space Operation are

  • PWICSO Identify duties and responsibilities of all personnel involved in confined space work under the WSH Legislations and Code of Practice.

  • PWICSO Identify confined space hazards

  • PWICSO Use Gas Detection Instruments for atmospheric monitoring

  • PWICSO Comply with Permit-to-Work system and safe work procedures when working in confined space

  • PWICSO Participate in an Emergency for confined space

 

Course Duration for the Perform Work in Confined Space Operations:

  • 14 Hours (Inclusive of Assessment)

 

PWICSO Assessment:

  • Written Questions

  • Practical Performance

  • Upon completion of the PWICSO course and passing the examination, a Statement of Attainment (SOA) from Skillsfuture Singapore (SSG) will be awarded.

 

PWICSO Price of Course:

Additional Information about the Perform Work in Confined Space Operation

Legal Requirement for Perform Work in Confined Space Operation Training

Under the Factories (Safety Training Courses) Order 2001 which came into effect in June 2001, all workers, including Singaporeans, must undergo a Safety Orientation Course (Manholes) before they are allowed to work in Manholes and other Confined Spaces. This is now under the Workplace Safety Health Act and its subsidiary legislations

A Confined Space worker or a Manhole Worker when about to perform work in confined space operations, as appointed by the Principal or Employer of a workplace, will play the role of either an entrant or an attendant.

As such the Confined Space Entrant has the responsibility to:
i) coordinate with the confined space attendant, confined space supervisor and confined space (manhole) safety assessor to ensure safe entry in and egress from the confined space or manhole,
ii) assess the working conditions in the confined space or manhole and evacuate the confined space or manhole when it is unsafe to work,
iii) only carry out prescribed work activities (ie perform the work that is allowed), for allowed durations, as approved on the entry permit.

 

The Confined Space attendant has the responsibility to :
i) coordinate with the confined space entrant, confined space supervisor and confined space (manhole) safety assessor to ensure entrants safe entry in and egress from the confined space or manhole,
ii) prevent unauthorized entry into the confined space or manhole,
iii) maintain regular visual and/or verbal contact with the confined space entrants
iv) assess the working conditions in the manhole and alert the confined space entrants to evacuate when the confined space or manhole is unsafe to work in,
v) alert the confined space rescue personnel to activate the confined space rescue operation.
