Port Dry Bulk Terminals hazardous

Access and Egress

Risk of:
·         Drowning.

·         Passing ships causing ship to move.

Biological Agents

Risk of:
·         Infection.
·         Adverse health effects.
·         Asphyxiation.
Possible causes:
·         Presence of insects, rodents, pigeons and other vermin.
·         Exposure to dust containing bacteria or fungi.

Chemical Agents

Risk of:
·         Health hazards e.g. by ingestion or inhalation.
·         Asphyxiation / death.
Possible causes:
Exposure to toxic, fumigated or corrosive cargoes:
·         Failure to notify that cargo has been fumigated due to lack of communication and consultation.
·         Inherent property of the cargo e.g. corrosive cargoes.
·         Cargoes liable to cause oxygen depletion e.g. forest products, metals, vegetable or fruit products.
·         Decomposition or bacteriological action on cargo giving rise to toxic products e.g. coal, bark, fishmeal and other types of wet fish.
·         Ammonium nitrate fertilizers can explode or decompose to release toxic gases.
·         Some coal products produce carbon monoxide or methane.
·         Cleaning holds for grain after discharging a dirty cargo e.g. use of degreasing chemicals.
·         Fumes from mechanized  plants and vehicles.

Confined Spaces

Risk of:
·         Asphyxiation due to lack of oxygen or being drowned in dry materials such as grain or other free flowing materials in which a person could sink.
·         Fire.
Possible causes:
·         Entry into an oxygen deficient hold, hold access way or trunkway.
·         Atmosphere in hold may be toxic, asphyxiating or flammable as a result of the cargo or may be formed during the process of cleaning, welding or painting.
·         Excess oxygen caused by leaking oxy/fuel gas cutting and welding equipment.
·         Oxidation of the cargo in the hold using up the oxygen from the atmosphere e.g. pig iron, wood chips and bark.
·         Failure to observe confined space entry and atmospheric testing procedures.
·         Failure to have a rescue plan.

Dust

Risk of:
·         Respiratory problems.
·         Sensitization causing effects such as asthma e.g. grain.

·         Spillage from (un)loading equipment.
·         Lack of dust control equipment i.e. engineered equipment.
·         Incorrectly operated and/or maintained (un)loading equipment causing excessive dust.
·         Unsafe system of work e.g. cargo being dropped from a height such as into the hold from the grab, from the back of truck when cargo tipped or stored on the terminal, from one conveyor to another or when a wall of residual material builds up and collapses from a bulkhead or between the frames in the hold of the ship or from the side of a hopper.
·         Sweeping cargo with a brush or air.
·         Inadequate communication between the truck driver and hopper operator resulting in truck driver driving away prematurely from the hopper.

Environmental Conditions

This includes tidal movements, wind conditions, heat, cold, ice, wind etc.
Risk of:
·         Increased risk of accident or incidents occurring.

·         Material / lumps of cargo falling from the conveyor belt of the ship loader or from the discharging grab onto the deck of the ship or the quay. A number of bulk cargoes such as quartz, iron ore, pig iron and steel scrap contain sizeable lumps which could cause death or injury if they fall from a height and hit someone.
·         Personnel on deck walking under the grab.
·         Unsafe system and/or unsafe lifting accessories for lifting equipment from the terminal to the ship e.g. whilst lifting mobile plant from hold to hold, lifting loading chutes, spouts and arms or lifting welding and other equipment into the hold to carry out damage repairs.
·         Cargoes falling from ship's structures, frames, beams, ledges and ladders.
·         Personnel lowering or raising equipment in and out of holds with personnel still at work underneath.
·         Personnel monitoring cargo operations standing too close to where the grab is working and at risk of being struck by grab or by a breaking grab rope.
