Abstract
This study aimed to, estimate the hazard involved during chemicals transportation using truck trailer from Alexandria to idku site.
This study was carried-out on 40 drivers that drive their petroleum Tank from Alexandria to Edku for determination of the risk hazards that may exposed to it during transportation of the petroleum oil from Alexandria to Edku.
This risk assessment method will utilize a matrix system that will evaluate the interaction between the main factors.
The results indicated that:
1-The most activity of a highest risk includes driving on the roads 19 (47.50 %), Loading and checking/securing the lashing/ valves after finish loading 4 (10 %), driving to the client’s 3 (7.50 %), driving into the site 3 (7.50 %), Stopping & shutting the truck down 3 (7.50 %),
2-The most activities of a highest risk identified were driver qualification 6 (4.55 %), gate opening not sufficient 5 (3.79 %), accident on the road 5 (3.79 %) and traffic congestion 5 (3.79 %).
3-Awareness level of a worker on occupational risk is closely related to providing proper knowledge and understanding of the subject. While, The results on the Hazard effect (Risk) cleared that, The hazards effects of a highest risks includes tank explosion 5 (3.79 %), delaying of arrival 3 (3.79 %), accident 5 (3.79 %).
4-The risk analysis results cleared that, the possible risk reached to 13 (52 %), followed by unlikely 9 (36 %0 and the likely risk reached to 3 (12 %). While, the severity level showed that, catastrophic level reached to 11 (44 %), Major level reached to 9 (36 %) and the lower severity observed in minor level 5 (20 %). While the (L*S) levels showed that, the higher (L*S) risks observed in High (L*S) 16 (64 %), followed by moderate (L*S) 8 (32 %) and extremely high as it reached to 1 (4 %), and in minor risk reached to 0 (0 %).
5-The results on the existing control measures cleared that, The highest existing control measures observed in Premobilization safety check of the truck 8 (6.70 %), Apply Spillage emergency plan 4 (3.30 %), Escort is required to control the trip 4 (3.30 %), Ensure your vehicle is suitable for the intended trip 4 (3.30 %), Journey management plan is required 4 (3.30 %)
6-While, The results on the risk residual cleared that, The higher risk residual according to likelihood observed in Medical treatment (off site) 20 (80 %), followed by Minor injury (first aid on site) 3 (12 %) and the lower risk residual observed in lost time injury 2 (8 %). Meanwhile, the higher risk residual according to severity observed in minor severity 11 (44 %), simple 8 (32 %)and the lower severity observed in major severity 2 (8 %) and catastrophic 2 (8 %). Meanwhile, the higher risk residual according to (L*S) observed in moderate (L*S) 23 (72 %) and Minor 7 (28 %).
7-The results on the dinstances of transportation using truck trailer from Alexandria to idku site cleared that, the higher risk incidences observed in the long distances of the transportation. The higher risk incidences observed in distances over 40-Km and reached to 15 % and constituted in accidents and delay , followed by the incidences at the distances ranged from 30 – 39 Km and constituted in fire incidences. While, at the distances ranged from 20 – 29 Km the risks incidences reached to 10 % and constituted in loosing and package 25 %.
8-While, the results on drivers’ urine analysis for detection of anesthetics cleared that, the most important anesthetics drugs include cocaine in urine, Amphetamine in urine, Benzodiazepine in urine, Opiates (Morphine) in urine, Cannabinoids and Tramadol in urine. Also, the results cleared also, no any driver take anesthetics drugs during driven its cars.
