Safety in the darkroom

There are some health and safety issues in the darkroom. The most commonly used chemicals are no more dangerous than household detergents and bleaches, some of the more specialized chemicals can be hazardous. Here are some do's and don'ts to make things safer.

Do's

• Wear gloves ( rubber or Latex), protective cloths and use eye protection.
• Wash spillage's to skin and eyes quickly with lots of water.
• Keep a tap hose for this purpose'
• Clearly label everything.
• Make sure there is good ventilation.
• Dispose of solutions safely' seek advice if needed.
• Mix chemicals slowly and in the right sequence.
• Filter water and home-made solutions to remove bits especially for film processing.
• KEEP ALL CHEMICALS OUT OF THE REACH OF CHILDREN.

Don'ts

• Eat, drink or smoke when mixing chemicals.
• Inhale dust from powders.
• Fail to read instructions and warnings first.
• Use kitchen scales for chemicals.
• Use metal containers, mixers and trays.
• Add chemicals together without knowing if the outcome is safe.
• Add water to strong acids or alkali's ( e.g. caustic soda-Na OH). Always add them to water not the other way round and slowly.
• keep large glass bottles on high shelves.

Darkroom layout



When setting out your darkroom it is best to set your work flow from left to right. By doing so you are less likely to contaminate the dry side with chemicals or water. You should keep the enlarger table separate from the development table. The dry side takes up less space than the wet side so can be put along a shorter wall. The support for the enlarger should be completely stable and set at a comfortable working level when standing. For a standing position the right height is 95cm (37").

A typical lay out

Remember electricity and water don't mix so take particular care when providing power for your equipment. If in doubt consult an electrician. It is not imperative that your darkroom has running water but ventilation is and will need a light proof grate.

This may sound strange but make sure that the illumination is sufficient to allow you to see round the room when printing.
