That is good to know. We have some grout we cannot get cleaned and we wanted to try some high concentration H202. I will have the wife ask to get some from the hair salon
The H202 is supposed to be food
grade to use with sanitizing seeds for sprouting. What ever "food grade" means. People are DRINKING this stuff diluted in water
35% H202 still can cause skin issues so I don't think you really want it on your bare skin. It is also a fire hazard if left to dry so it would have to be stored and used carefully.
Hmmm, I got curious and checked the ERG(Emergency Response Guide. I should have done this over the weekend. The ERG is used by first responders to identify the characteristics of chemical spills and the proper response. One can download the ERG for free, just google
it. You can look up a chemical by its name as well as it's guide number.
Fro H202 20-60%, here are some tid bits from the ERG:
- Keep combustibles (wood, paper, oil, etc.) away from spilled material.
- Do not touch damaged containers or spilled material unless wearing appropriate protective clothing.
- Remove and isolate contaminated clothing and shoes.
- Contaminated clothing may be a fire risk when dry.
- In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes.
- These substances will accelerate burning when involved in a fire.
- May explode from heat or contamination.
- Some may burn rapidly.
- Some will react explosively with hydrocarbons (fuels).
- May ignite combustibles (wood, paper, oil, clothing, etc.).
- Containers may explode when heated.
- Runoff may create fire or explosion hazard.
- Toxic by ingestion.
- Inhalation of dust is toxic.
- Fire may produce irritating, corrosive and/or toxic gases.
- Contact with substance may cause severe burns to skin and eyes
Me thinks I will not have this on the boat.
I make my own beer
and use a sanitizer called Star San. Star San is a contact sanitizer and works really well. I have not had a contaminated batch of beer
. Star San is sold as a concentrate and a few ounces makes a few gallons of sanitizer. I small bottle will last years. Star San will kill E Coli and other bad bugs according to the creator but I did not see anything about killing Salmonella.
We will use Star Sans to sanitize the seeds/beans and stay away from H202.
