Five Parties Convicted for Failing to Ensure Workplace Safety - WSH Bulletin

27 Apr 2010

Five Parties Convicted for Failing to Ensure Workplace Safety
Two companies from the marine industry and three of their employees were convicted on 1 April 2010 for failing to ensure workplace safety. The convicted parties were fined a total of $485,000.
One of the companies was responsible for the death of three workers and injuries sustained by 10 others in two separate incidents in 2008. In the first incident, the company was engaged to install hydraulic pipes on a vessel. A fire broke out on the vessel and injured four workers. It was found that the project manager had allowed compressed oxygen to be used to test the pipes. The pipes' rusty and rough interior generated heat when the pressurised oxygen passed through them. The heat, combined with the oxygen, rust and lubricating oil found in the vicinity, led to the explosion.
In the second incident, two months later, a flash fire broke out on a vessel during spray painting works at the company's premises. The accident left 3 workers dead and six others injured. Investigations found that the company did not effectively ventilate the tanks to ensure that flammable vapours generated from the spray painting works did not build up. The ship repair manager had also approved the permit-to-work without ensuring the implementation of all safety measures, e.g. preventing workers from bringing in unsafe torchlights, which could have been the ignition source.
The second company convicted was responsible for an accident on board a ship that claimed two lives, and injured another. The workers were assigned to clean a tank and they entered it even though it contained a high concentration of toxic Hydrogen Sulphide gas. Investigations revealed that the company had failed to provide them with safety equipment such as breathing devices and personal gas monitors. One of the supervisors had also told the workers to enter the tank even though it was dangerous to do so.
Chairman of the Workplace Safety and Health Council, Mr Lee Tzu Yang said the deaths and injuries in the cases are a "sombre reminder" of the workers affected by poor safety standards and a disregard for safety rules. "Each of the five workers who died had unfulfilled dreams and families who will miss them everyday. Industry players must constantly remind ourselves that we have a responsibility to ensure the safety of our workers. At no time should anyone disregard any safety measures so as to take an easier route to complete a job. In each of these cases, someone had ignored important safety measures," he said. On behalf of the WSH Council, he urged all stakeholders to think about the impact of one's actions and to always keep safety foremost on their minds.

Working in Hot Environment - WSH Bulletin

22 Apr 2010

Working in Hot Environment

Workers who are exposed to extreme heat or work in hot environment may be at risk of heat stress. Heat stress can result in heat disorders such as heat stroke, heat exhaustion, or heat cramps. As such, it is important for employers to be able to identify symptoms of heat disorders, and determine the level of thermal stresses that workers are exposed to.

This Bulletin provides information on managing heat disorders, and the assessment of thermal stresses associated with work in a hot environment.

Drop in Workplace Injuries & Occupational Diseases - WSH Bulletin

22 Mar 2010

2009 WSH Statistics Report Show Overall Drop in Workplace Injuries and Occupational Diseases

The WSH Council and MOM have announced the 2009 WSH Statistics Report which shows a drop in occupational diseases and workplace injuries reported across the board for 2009. The number of occupational diseases fell by over 45% and the total number of work injuries dropped by 2.1%. This is the first drop in overall work injuries reported since 2006.

The number of fatalities saw a 4.5% increase, and the fatality rate increased from 2.8 deaths per 100,000 persons to 2.9 in 2009. This is the first increase since 2005 and underscores the need to strengthen efforts on preventing workplace fatalities. There was also a 3.3% increase in actual man-days lost due to serious incidents. The traditional sectors like construction and marine sectors accounted for most of the fatalities (63%) in 2009 though new sectors such as hotel and landscape also saw 10 fatalities, up from zero in 2008.

WSH Council Chairman Lee Tzu Yang highlighted that while overall number of work injuries are down, the Council is concerned about the increase in work fatalities. He added that the Council will pay attention to both higher hazard sectors such as construction and marine, as well as less familiar sectors such as hotels and other service activities. As WSH and productivity are closely intertwined, having safer practices and outcomes will also contribute to productivity gains. As such, the WSH Council urged the industry to take a relook at their WSH practices and keep workers safe at work, while driving productivity.

MOM’s Commissioner for WSH Ho Siong Hin added that MOM will focus enforcement checks in areas of concern and urged both employers and employees to do their part to ensure workplace safety.

WSH Alert – 2 Workers Killed in a Chemical Explosion - WSH Bulletin

8 Mar 2010

Incident

On 23 Jan 2010, an explosion caused the roof of an atmospheric Diethylene Glycol (DEG) storage tank to be blown off. Two workers who were installing nitrogen pipelines on the tank roof at the time of the accident were killed. Investigation is still in progress.

Figure 1: The DEG storage tank, which is about 6m in diameter and 20m high.

Figure 2: Roof of the tank that was blown off and landed on a field outside the premises.

Recommendations

1. Conduct risk assessment: Prior to the start of work, a risk assessment should be carried out to determine the potential hazards and risks that might arise during the installation or replacement of a piping system. DEG has a flash point of 138 ºC (closed cup) and 143 ºC (open cup). Control measures and safe work procedures must be established to mitigate the risks, and be communicated and implemented to ensure the safety and health of the workers involved. Some of the hazards relevant to this incident include:

a) Excessive built-up of pressure in storage tank due to faulty breather valves
b) Hazards associated with hot work
c) Falls from height while working on top of the tank

2. Ensure proper supervision: It is important to ensure that any pipe replacement works are carried out under the close supervision of a competent person with adequate knowledge of the storage system, properties of the substances used and their associated dangers.

3. Establish safe work procedures: Safe work procedures must be appropriately documented to enable workers to identify the valves correctly, and to assist them on the proper steps to operate the different valves safely such that valves will not be opened or closed erroneously.

4. Inspect vessels / pipes regularly: Under the Workplace Safety and Health (General Provisions) Regulations, it is the duty of the owner of a pressure vessel or pipes that contain or convey hazardous substances to ensure that they are properly inspected before use. Thus it is important to inspect the valves, piping systems and storage tanks regularly to ensure that they are in good condition. Faulty valves must be reported to the supervisor who will assess if it is safe to continue with the work.

5. Check storage pressure: Workers are allowed to work on top of a storage tank only if the pressure inside the tank is known and it is safe for them to do so. Appropriate pressure gauges should be installed at strategic locations to indicate the pressure within. Whenever practicable, pressurised tanks should be purged to safe atmospheric pressure level before works are carried out at the top of the tank.
