9 Atmospheric contaminants

-Install local exhaust ventilation to the source of

-Air quality monitoring program-Training for workers to work in

-Respiratory masks, eye protection

the contaminants such environment

Control the hazards and risk to ALARP (As Low As Reasonably Practicable) by getting information through meetings, feedback session, site inspection, document review (SWP, method statement) and continuous monitoring methods. Regular maintenance and testing of emergency response procedures and equipment are conducted to ensure that they are in good condition and preparedness eg. Monthly checks on the fire equipment, fire evacuation drill twice yearly.

2. Formulation of control measures implementation plan

Firstly, the management need to set up a working committee to carry out the implementation plan. The committee members may happen to be the same as the same safety committee. The members should comprise of personnel from the management staff, supervisory, operations and administrative staff.

The recommended personnel to sit in this committee are:

- Project Manager (Management staff)- Supervisor, Engineer (Supervisory)- Foreman, worker (Operations)- HR officer (Administrative staff)

The roles and responsibilities of the working committee are listed in the table below.

S/N Committee member Roles & responsibilities Remarks1 Project Manager -Providing resources such as financial, time and manpower

-Plan, manage and control the implementation plan-Delegate roles and responsibilities to the members-Review of control measures and risks-Communicate the progress of the plan to the senior management (director)

2 Supervisor, Engineer -Implementation of control procedures- Communicate the plan to the workers, employee- Monitor and report the effectiveness of control measures - Conduct inspection and audits to ensure effectiveness- Getting feedback from the workers, employees

3 Supervisor, Engineer -Implementation of control procedures- Communicate the plan to the workers, employee- Monitor and report the effectiveness of control measures - Conduct inspection and audits to ensure effectiveness- Getting feedback from the workers, employees

4 HR officer -Arrange training for relevant employee ( mandatory and in-house)-Coordinate with external party such as government agencies and consultant -Keeping and updating records.

The prioritization of action items and schedule are based on the risk level, availability of resources and impact on production schedule. Therefore list down all the action items first, then put down their risk level if it is not done and how big is the impact if it is not done. The management should schedule to work on those action items that provide the highest impact on reducing the risk first.

In some companies, production schedule may be hindering the regular maintenance of electrical appliances as any shutdown will cause great impact in the output. For such cases, it is recommend to have minor shutdown for example every quarter for half a day and major shutdown for one week of schedule maintenance.

Nevertheless, financial resources may be a factor that slow down the progress of the control measures implementation plan, eg. Installing machine enclosure may be quite costly.

It is important to monitor the effectiveness of the control measures so that it can be review and improved when necessary. Monthly review meeting to be conducted to discuss on the inspection finding, feedback and data collected.

The timeframe given to implement the action plans need to be reasonable. Eg. Training of the worker to operate a new machine may need 1 week at least.

3. Describe how to raise attention (using flowchart) to the stakeholder on the hazards identified in different stages of construction projects.

KH Pte Ltd to construct an underground valve chamber at PUB West Waterworks. The chamber dimension is 6m length X 4m width X 5m height.

Every stakeholders involved in the construction are responsible for safety.The various stages of the construction process, requires proper planning to ensure integration of the safety and health control measures with the work processes, so that construction of the underground chamber can be carried safely in a timely manner.

4. Illustrating the appropriate ways to communicate the control measures and implementation plan to the relevant stakeholders.

Communication of the control measures and the implementation plan to the relevant stakeholders can be through:

1. Operations meetings (for Management personnel, Suppliers, Clients, Consultants)

2. Consultation meetings (for government authorities)3. Safety Committee meetings (for WSH personnel, Supervisor,

Foreman) 4. Safety briefings, daily toolbox meetings (for workers and contractors5. Training sessions (all employees)6. Notice board (all employees)7. Internet, email (those employees with computer)

5. Show at least six methods to monitor the implementation of control measures.

The following are ways to monitor the implementation of control measures:

i) Physical inspectionii) Interview of personneliii) Document reviewiv) Medical surveillancev) Compliance auditsvi) Periodic risk assessment

6. Applying the control measures effectiveness criteria to evaluate the effectiveness of control measures

The criteria to evaluate the effectiveness of the control measures are:

- Reduced risks (if not eliminated)- Reduced incident, accident reported- Reduced waste / unwanted materials generated- Well accepted by the user- Positive results reproducible- Reduced loss in production down time- Improved safety awareness among employees- Reduced non-compliance reported during inspection audits

7. Prepare a status report of an implementation plan.
