What are the hazards and safety behaviors one must observe when operating Electrical machine •

Table of Contents

Poor house keeping: not properly arranging the line after production, speels all over the plants, e.t.c can cause accident on the plants.
Falling hazard: Falling hazard include stuffs like a falling ladder, falling gadgets, falling gas cylinder or any other equipment that can fall on a person, that has the potential of causing death, injury or damage to someone.
Wrong lifting: powered tools not held well or too heavy. Even wrong usage of equipment or tools can be an hazard.

Follow the employer’s operating instructions concerning machine operation
Read the current operating manual before doing any work on the machine.
Observe all applicable safety regulations. Take all necessary safety precautions to prevent hazardous situations when operating the machine/system.
When you turn ON the machine, make sure that no one else except you is near the machine or in the danger zone, particularly when jogging the machines while the guard doors are open.
Access danger zones ( zones which are behind protective devices) only through entrances designated by the manufacturer and only after having properly/ shut down the machine and having loaded it
This is to prevent it from being turned ON again
Before starting work, check the safety devices and the machine for visible defects
If the defects pose an operational safety hazard, do not operate the machine respectively switch it off
If the machine has any defects, especially those which affects safety, inform your superior, and when changing shifts also inform the person who takes over the shifts
Never actuate or tamper with control components and monitoring device, etc….if you’re unauthorised or do not know how they work.
Never wear jewellery (rings, bracelet, etc) which could get caught in machine parts. Long hair should be tucked under an hair net.
Never allow the machine to run unattended.
Wear a fall arrester when working in great heights.

HAZARDS AT THE MACHINE: infeed

Risk of injuries due to chemicals (skin/eye injuries)
Risk of injury due to high temperatures ( the temperature is above 45⁰c in many zones of the bottle washer)
Risk of infection due to microorganisms.
Risk of injury due to slipping on wet surfaces
Risk of injury due to electricity (when electronic components are defective in combination with moisture)
Also as a technician you should ‘observe the safety instructions of the chemical supplier

Risk of injury due to chemical burning (skin/eye injuries)
Risk of injury due to high temperatures ( the caustic temperature is around 80⁰c)
Risk of injury due to contact with non-insulated machine parts (e.g: heating valves, heating piping)
Risk of injury due to hot vapours (skin/eye/lung injuries)
Risk of injury due to label press (injury to hand)
Risk of injury due to label conveyors (injury to hand)
Risk of injury due to slipping ( caustic is slippery)
Risk of explosion due to hydrogen gas(H2) – if materials with tin foil are fed into the machine the aluminium decomposes in the caustic solution and releases hydrogen gas. This gas combines with oxygen in the air to form an explosive mixture which in even a small concentration can easily be ignited.

Risk of injury due to cullet (serrations, eye injuries)
Risk of injury due to mechanical movement (crushing hazard)
Risk of injury due to noise (hearing impediment)
Risk of injury due to caustic remains in the container (caustic bottles, sealed bottles, which have been used for other than the intended purpose, e.g solvent solution and others)

Risk of injury to the eyes due to misguided spraying
Risk of injury due to chemical burning
Risk of injury due to heat (especially in the post caustic)
Risk of injury due to mechanical movement (crushing hazard especially with clock filter conveyors)
