Safe and Sound - Product Safety

Caution is better than Risk, Prevention is better than cure. using the the right tools for a job alone is not sufficient; You have to get trained and informed about its proper use and safety precautions.

When we Design a Product or Develop further a design; we have to integrate Product Safety into the usage method and improve usability and safety. Product also has to be Engineered in such a way that manufacturing it does not pose hazard to the worker.

Safe and Sound - Product Safety

Product Safety
  • Product should not give even the lightest shock, Even metal parts on user side to be laminated.
  • High energy circuits never enters analog and digital circuit areas without Opto or other Isolation.
  • Gadgets, Furniture, Tools and Storage Units should not cause injury. Rounded Edges, Non Toxic.
  • LED and Lasers can damage Vision, welding too. Use Protective Filter Glasses. After a comment by John Bump
Worker Safety
  • Helmet, Goggles and Face/Respiratory Mask when working with power tools/ abrasion and large objects.
  • Crepe Bandage, Neoprene Ankle/Knee/Thigh Support when pushing or pulling or Physical Exertion.
  • Waist/Back Support Belts and Straps to reinforce back/spine while doing Heavy Lifting or Movement.
  • Waistband Thick Belt or Traditional Sash helps Posture and prevents slipped disc or spinal injury.
  • When using a Knife, Sharp Tool, Pointed Tool or Drill; cut/bore away from your body or finger/leg not towards.
  • Use Long Riding Leather/Synthetic Boots when working in chemical plants and heavy industry.
  • Cross Ventilation and exhaust fans important if even little chemical fumes are generated in your work.
  • Soldering, plastic forming and even for some kinds of material processing. Good Ventilation or Masks needed.



Safe and Sound - Product Safety

Workshop Safety
  • Fire hazard and Air pollution in the workplace is the most important two dangers, Electricity is third.
  • Use Leather Boots when working with high voltage, also silicone flexible gloves or Latex Gloves.
My Recent Lessons -

Wear ear muffs when Noise present in surroundings to avoid distraction. When your own tools/work create too much noise, then also ear muffs protect ears, give some allowance/filter for audio feedback
  • Cut away from you, not towards. Sharp tools and Power tools keep job at a distance. Watch for Splinters.
  • Both Legs and at least one hand insulated when working with High Voltage.
  • Use the right tool for the right job. Do not use cutting plair like a hammer.
  • Do not use Teeth, Legs etc. as tools. Only Iron and Steel should face the Job.
