FIRST SENTENCE UNDER THE NEW WSH ACT

The new Workplace Safety and Health (WSH) Act saw its first sentence in April 2007. Leelloyds Marine Engineering Pte Ltd was fined S$100,000 and Mr. Low Lye Wah (Supervisor) was sentenced to three months’ imprisonment.

Struck by Falling Objects - Dislodged Suspended Bag Claimed Worker's Life!
5 March 2006, 11.40am - after finishing their shift duty on board a bulk carrier vessel, four workers of Leelloyd and the supervisor, Low Lye Wah (Low) were preparing to pack their work tools and transfer them onto a ferry boat alongside the vessel. Low was responsible for rigging and lowering four bags of loads from the vessel onto the boat 15 meters below.
The first three loads were lowered to a reasonable height of about 1m from the boat deck before the boat was steered near the vessel for the workers on the boat to pull the load onto the boat. However, Low did not wait for the boat to move away from the shipside as he lowered the fourth load. Instead he started to lower the fourth load while a worker was trying to untie the third load. This put the workers on the boat beneath a suspended load and exposed them to the risk of being struck by falling objects. Subsequently, the fourth load weighing about 15 kg came loose from the rope's knot and fell a distance of about 10m, hitting a worker James Balang on the head. James Balang succumbed to his injuries in hospital on the same day.

Findings of Ministry of Manpower’s (MOM) Investigation
1. The method of lowering the fourth load from 15 m above the boat deck was unsafe as it was carried out using the other end of the rope while another worker on the boat was trying to untie the third load on the same rope. This exposed the workers on the boat beneath to the risk of being hit by falling object.
2. The supervisor Mr. Low Lye Wah is a trained lifting supervisor and a qualified rigger. He was therefore, fully aware of the safe work procedures and precaution needed and understood the danger that his actions posed to the workers. Instead, his reckless act had endangered the safety of the workers, when it was incumbent upon him as the supervisor to look out for their safety. This reckless act of him has resulted in the death of his worker.
3. The company Leelloyds had previously implemented safe work procedures when working on another similar project. Even though it was familiar with the safe work procedure, it did not take reasonably practical measures to ensure the safety of the workers in this incident.
Summary of the case
While lowering work tools using a rope tied to a bag from a bulk carrier vessel onto a boat, the 15 kg load came loose from the rope's knot and fell a distance of about 10m, hitting a worker James Balang on the head. He succumbed to his injuries in hospital on the same day.
The Sentence
Leelloyds Marine Engineering Pte Ltd was fined S$100,000 and Mr. Low Lye Wah (Supervisor) was sentenced to three months’ imprisonment under the new WSH Act in April 2007.
Advisory Note(Please note that the advisory note is provided for the benefits of enhancing workplace safety and health, in no way the information is to be misconstrued as implying any liability on any party)

1. Investigations into the accident revealed that one of the root causes of the accident was the lack of proper planning and supervision of the tasks being performed. All employers and contractors are advised not to be complacent during any lifting operation. All lifting operations should be properly planned by a competent person before the actual execution.
2. Under the WSH (Risk Management) Regulations, comprehensive risk assessment shall be conducted for all work processes to eliminate or control risk through detailed plans/procedures for work to be carried out. Arising from the risk assessment, appropriate safe work procedures shall be developed and implemented. Risk Assessment guidelines and other relevant references are available at the MOM Website and WSHAC Website.
3. It is essential for risks to be eliminated or reduced “at source”. If a risk cannot be controlled completely by engineering measures, it is necessary to protect the employees by administrative control or personal protection. The control of hazards and reduction of risks for the above accident can be accomplished by following the Hierarchy of Control.
a) Engineering Controls
Engineering controls are physical means to limit the hazard. These include structural changes to the work environment or work processes, erecting a barrier to interrupt the transmission path between the worker and the hazard.
- All tools and other items should be lifted or lowered using the ship’s crane or derrick or other safe and effective means. These loads and items should be placed in sling bags that are designed to carry loads of specific capacity.
- The sling bag can be anchored directly onto the crane’s hook or attach to the hook by proper lifting gear, thereby eliminating the need for a tying knot.
- All statutory lifting equipment and lifting gears must be inspected and certified safe for use by an Authorised Examiner for lifting equipment. Lifting equipment must not be loaded beyond its safe working load under any circumstances except for the purpose of testing and examination by the Authorised Examiner.
b) Administrative Controls
These reduce or eliminate exposure to a hazard by adherence to procedures or instructions. Documentation should emphasize all the steps to be taken and the controls to be used in carrying out the activity safely.
- Workers who are on board the ferry should stay in the cabin until the load is lowered at the deck level. Enforce the ruling that no one is allowed to stand below any suspended load.
- Effective communication through hand signals, voice communication, loud hailers or sign languages must be maintained at all times between the parties concerned during lowering or hoisting of any load.
- Qualified Lifting supervisors who have successfully completed a training course approved by MOM must be appointed by the occupier before the commencement of any lifting operations involving the use of any cranes.
c) Personal Protective Equipment (PPE)
This should be used only as a last resort, after all other control measures have been considered, or as an additional protective measure.
- Suitable Personal Protective Equipment (PPE) must be provided and used by the workers. Safety helmet approved by an accredited testing body must be worn whenever there are hazards of falling objects.

Fire on Storage Tank

A flash fire occurred at the ground level of two storage tanks containing marine slop oil. This resulted in a flashback which ignited one of the tanks and ruptured its tank top.
A worker who was working within the proximity of the tanks suffered serious burns and subsequently succumbed to his injuries.

Advisory Note- tips for safe storage of flammable chemicals(Please note that the advisory note is provided for the benefits of enhancing workplace safety and health, in no way the information is to be misconstrued as implying any liability on any party)

1. All storage tanks designed and constructed for containing flammable liquids shall conform to acceptable Singapore or International Standards.
2. Fixed storage tanks containing flammable liquid should be equipped with pressure-vacuum vents to allow for changes in pressure due to filling or withdrawal of product and to breathing of the tank due to atmospheric changes. This minimises vapour emission to the environment.
3. Floating roof tanks can be used for storage of flammable liquid to minimise product loss and fire and explosion hazards.
4. Storage tanks should be earthed. This helps prevent a static electrical discharge which might start a fire during filling or decanting.
5. No source of ignition (e.g. open flames, hot surfaces and sparks) shall be allowed at the storage area. Electrical installations and appliances in such area shall be of explosion-proof type.
6. Suitable fire fighting equipment or facilities shall be readily available to contain or mitigate any possible fire.
7. A risk assessment (RA) shall be conducted and safe work procedures (SWP) shall be developed for all work activities.
8. Workers shall be informed about the risk and hazards involved, and shall be trained in RA and SWP. They shall also be trained on and drilled in emergency response and spillage control.
9. Appropriate personal protective equipment (e.g. respirators, goggles, gloves and aprons) may be required to ensure the health and safety of workers working in such premises.

Validity of CSOC and SSIC Certificates

Based on revised requirements, the validity of course certificates for the Construction Safety Orientation Course (CSOC) and Shipyard Safety Instruction Course (SSIC) issued to workers will depend on their period of employment in Singapore. A worker with less than 6 years work experience will be issued with a 2-year certificate while a worker with 6 years or more relevant work experience will be issued with a 4-year certificate.

With effect from 2 July 2007, employers and employment agencies can check via the Ministry of Manpower (MOM) website URL link if their employees have attended the above courses and if they will be issued with certificates valid for 2 or 4 years. This information can then be conveyed to the ATP to facilitate the issuance of the certificates.

Three workers died in flash fire at a heat exchanger

A fatal workplace accident took place this year while a group of workers were de-blinding a pipe of a heat exchanger when flammable liquid suddenly flowed out from the pipe. The workers attempted to dilute the liquid with water but a fire broke out and engulfed the area near the heat exchanger. 3 workers were killed.

Advisory Note for blinding or de-blinding work(Please note that the following advisory note is provided for the benefit of enhancing workplace safety and health and in no way should the information be misconstrued as implying any liability on any party)

De-blinding is the process of removing metal plates inserted in-between pipe segments. The metal plates are usually inserted to prevent flow of substances from one part of the piping system to another part of the system.
1. Conduct risk assessments and establish safe work procedures for blinding and de-blinding of pipes during maintenance of process equipment. Factors such as valve leakages should be considered in the risk assessment. Click HERE to download the Fire Risk Assessment Guide produced by the National Fire Prevention Council of Singapore (NFPC).
2. Establish effective emergency procedures in response to events such as unintended chemical release or fire.
3. Ensure that fire escape routes are readily accessible.
4. Ensure that fire fighting equipment and containment for chemical spillage are readily available.
5. Ensure that sources of ignition such as hot surfaces or hot work are not present in the vicinity where blinding, de-blinding or pipe dismantling work is carried out.

WSH (Workplace Safety and Health Officers) Regulations

The WSH (Workplace Safety and Health Officers) Regulations will take effect on 1 August 2007.

The Regulations will replace three subsidiary legislations under the former Factories' Act:
(a) Factories (Qualifications and Training of Safety Officers) Notification;
(b) Factories (Registration and Duties of Safety Officers) Regulations; and
(c) Factories (Safety Officers) Order.

The key change in the new regulations is the removal of the distinction between a full-time and part-time WSH officer. It adopts an outcome-based approach where occupiers decide on the extent of appointment for the WSH officers, whether part-time or full-time.

Workplaces required to appoint a WSH officer are stipulated in the Second Schedule of the Regulations, including:
(a) Shipyards in which any ship, tanker and other vessels are constructed, reconstructed, repaired, refitted, finished or broken up;
(b) Factories used for processing petroleum or petroleum products;
(c) Factories in which building operations or works of engineering construction of a contract sum of $10 million or more are carried out; and
(d) Any other factories in which 100 or more persons are employed, except those which are used for manufacturing garments.
