Bichromate sensitser is very poisonous. Dont know about cancer though. Its very fast in exposure time. You should only sensitze what you can use in a few hours. Use safe lights. Keep the coated screens is a light proof box or room I believe you can even get bichromate sensitizer in the US any more. Dont inhale the sensitizer and wash your hands after handling it. | |
