Recently bought a DIY product which had a safety sheet enclosed.
It was headed by symbols advising eye protection, hand protection, respiratory protection, & hearing protection.
The safety instructions carried on; "Handle with care. Store in dry conditions away from direct sunlight. Do not expose to hot, cold or damp conditions. Ideal storage is 18-22 C and 45-65% humidity. Store in original packaging and keep away from direct contact with windows, doors & floors".
Can anyone guess what the highly dangerous, unstable product was?
First correct answer wins a Medway Handyman fridge magnet :-)
