UNIT IGC3 – THE HEALTH AND SAFETY PRACTICAL APPLICAITON
Introduction including overview of area inspected and activities taking place I inspected a site which is being constructed by HYUNDAI Construction,Abu Dhabi for finding occupational health and safety procedures adopted, on 11/12/2015 from 10 A.M. to 4 P.M. For over 18 years, Hyundai Constructions has been synonymous with quality construction. The site is a 10 storied building under construction. Two floors have already been built and roofing activity for third floor is going on. There are 30 foremen, 2 Supervisors, a Site Engineer, and a Site manager. The working site consists of:
A Crane, a Concrete mixer, a hydraulic excavator, a tractors and welding machines. A storage area for construction material (cement, wood, paints, solvents, etc…). A cabin for Site engineer and manager to supervise the work activities often.
The work being carried out is construction of retaining walls in the ground floors, constructing parking lot, welding activity, electrical wiring installations and painting of constructed floors.
This report identifies the important areas which need modifications as listed below. These are listed in the order of importance. Fire safety Fire risk arises from damaged electrical wiring and storage of flammable substances like welding gas (oxy acetylene) cylinders, paints, wooden materials, solvents, wooden materials are stored with inadequate protection. Proper segregation of these materials is needed with adequate labelling and safe storage.
Machines like cranes and excavators are not used and maintained according to the manufactures recommendations. Injuries can be controlled by removing damaged slings from the workplace and proper procedures should be adopted while using machinery. Working practices Appropriate PPE is not used while painting and welding; allowing excessive personnel on the scaffolds; Barricades are not installed after excavation, etc, are some of the unsafe practices found during the inspection. Proper inspection, training and supervision are needed.
Welding hazards Risk of electrocution and burns founded from welding activity which is performed wet conditions and workers not wearing proper PPE. The welding hazards are controlled by adopting work permit system and providing training and required PPE to the welders. Fall hazards Several fall hazards are identified in the work site. Workers are found on the heights (scaffolds) without personal fall arrest systems. Equipment and tools are placed on the scaffold under which no barricades are provided. Sufficient protective equipment and guarding systems should be provided which reduces the risk of accidents in the work site. Improvisation of job activities by adopting the safe work practices will reduce the risk of accidents in the work site. This in turn improves the efficiency and productivity. A lot of time and investment is saved in connection with staff training, accident investigation, and compensation claims.
The suggestions made in this report can be exercised directly by the staff only and at relatively little cost. Failure to implement the suggestions made will cause damage to reputation and negative publicity. This in turn will make a difference to the financial success. Management should also view the issues in terms of humanity and moral dimension. Main findings of the inspection This report identifies the important areas which need modifications as listed below. Fire hazards (observations 19, 20, 21) A number of fire hazards were present on the worksite specially inspecting store room: Damaged electric wiring and components, chemicals are stored in bulk quantities without proper ventilation and welding gas cylinders are stored under poor condition without security. These conditions may lead to major fire explosion and also to huge property damage, severe injuries or death. These conditions are violation of rules stated in Article 16 of ILO Convention C155 and more specifically the obligations mentioned in ILO Recommendation R164 for the employer are breached. Electric wirings and components to be replaced by authorized persons and welding gas cylinders should be separately stored in blocks in upright position and secured with chains. Store employees should be trained in segregation and proper storage of materials, regular inspections should be conducted by a competent person. Machinery and equipment (observations 3, 4, 6) Several items of machinery and equipment are identified to be in dangerous state due to the poor use and maintenance: Excessive noise was generated by backhoe during excavation to construct parking lot in open area of the worksite. Damaged slings of Cranes are found in use for lifting heavy objects (gas pipes) to be fitted in the second floor. Jack hammer which is been used to drill the concrete for pipe laying in the ground floor is found physically damaged. These conditions may result in severe injuries or deaths leading to significant fines or prosecutions and also to large compensation pay outs. These conditions are violation of rules by the employer mentioned in ILO Article 10 (a) of R164. Jack hammer should be repaired; Backhoe should be under regular maintenance, damaged slings should be immediately replaced.
Proper training should be provided for the operators of carne, backhoe and staff and regular inspection should be conducted by a competent person.
Working practices (Observations 1, 2, 11, 15) Due to the lack of safety awareness by workers on the site a number of unsafe practices are noted, which includes: Failure to wear sunglasses for avoiding hot temperature exposure (direct sunlight). Respirators are not found in use to avoid dust from excavation activity. Operator fails to unplug the power source while replacing the discs of grinder during floor smoothening work. Supervisor allowing excessive load and workers on scaffold. This is a possible breach of requirements to provide training to the workers in their respective job activities. These indicate the violation of rules stated in ILO Convention C155 and R164. Suitable sunglasses and respirators should be provided to the workers who are exposed to direct sunlight and dust. Proper training should be provided to grinding operator and scaffold supervisor to identify the possible hazards of equipments.
Welding hazards (Observations: 7, 8) Due to the lack of safety awareness among the workers and supervisors welding activity is performed in wet conditions which pose a great risk of electric shock and electrical burns. Welders are at great risk of radiation and skin burns as they are not wearing proper PPE. These conditions represent the violation of rules stated in ILO Article 16 of ILO Convention C155. Management should implement the work permit system where hot work (welding) is performed. Suitable Personal protective equipment i.e. Face shields, respirators and gloves are provided to the welders. Proper training should be provided by a competent person to welders on hazards of welding.
Fall hazard (observation 16, 17) Falling of materials has been identified in the working area under the scaffold, used for roofing work of the third floor.
Workers are identified without fall protection on scaffolds while carrying out the roofing activity. This may cause their fall from height leading to severe head and body injuries and sometimes even fatality. This condition may result in severe injuries or deaths and give out compensation apart from possible sanctions from authorities. This indicates the breach of rules mentioned in Article 16 of ILO Convention C155. Management should provide screens for placing on the guardrail system and area under scaffold should be barricaded. Management should allocate a full time supervisor to monitor the task and to restrict the entry. Proper fall protective equipment should be provided to the people working on scaffolds. Training in fall protection should be provided by a competent person to the staff. Conclusions Little attention towards safety issues are found to be paid in implementation. Due to poor maintenance and lack of safety knowledge employees are working under hazardous conditions. Lot of energy is found to be put in for carrying out easy tasks. Stress and strain are the immediate consequences. Property damage, loss of reputation and bad publicity are the issues that rise later. The five areas mentioned in the report need immediate attention. Appropriate suggestions have been made for some observations. Implementing these practices assumes very little cost and can be actioned by in house staff only. It is certain that costs required for facing the consequences of the hazards resulting due to these mentioned will be more tham their implementation cost.
