Is the chemical safe?

Chemicals usually change when they are exposed to air because they oxidize. Metals like iron and copper oxidize. As iron oxidizes, it turns into a reddish-brown substance called iron oxide (rust). Copper oxidizes to make a green substance called copper oxide. Since copper is a major component in bronze, bronze turns green when exposed to air as well. This is why the Statue of Liberty is green. Many of these chemicals are not dangerous but many are but not many come in contact with us.

It is a chemical reaction.

The easiest way to find out the answer to that question is to look up the MSDS.  It gives all the information you need about it's toxicity, reactivity, etc.  A lot of chemical supply companies have MSDS on their websites, and I think there might be a government website that has MSDS accessible online, but I'm not sure.

Keep the chlorine level at 1.5 ppm and shock regularly and it is not a problem. It is, however, not socially acceptable. But no one is going to get a disease from it-- IF the chemicals are maintained properly. We "carry" a lot of foreign matter into a pool when we go in. Saliva, dead skin, hair, dandruff, etc., etc. That's why pool sanitizers are necessary! Plus, a pool being an open vessel, is constantly bombarded with air borne contamination. Rain water does infinately more damage to a pool than a little urine.

I suspect you used Naphtha, a volatile liquid used for cleaning items and removing oil and grease. This is a relatively safe chemical with the exception of its high volatility and flammability. However, anything is possible and if you have doubt or issues, I suggest you see a medical professional.

people throughout the United States could face "a potential risk of developmental and other adverse effects" from exposure to low levels of a chemical used in making the nonstick substance Teflon.\nA controversial chemical used by DuPont Co. to make the nonstick substance Teflon poses more of a cancer risk than indicated in a draft assessment by the Environmental Protection Agency, an independent review board has found.\n\nThe EPA stated earlier this year that its draft risk assessment of perfluorooctanoic acid and its salts found “suggestive evidence” of potential human carcinogenicity, based on animal studies.\n\nIn a draft report released Monday, the majority of members on an EPA scientific advisory board that reviewed the agency’s report concluded that PFOA, also known as C-8, is “likely” to be carcinogenic to humans, and that the EPA should conduct cancer risk assessments for a variety of tumors found in mice and rats.

There are a Chemical disposal company. Safe disposal so doesn't effect earth

Yes- by all means.  It is just a hosting site and it is completely safe.

I'm looking for more information, but LRS3 appears to be just a trade name for one company's application of Teflon(R) to their cookware.   Teflon has been a topic of conversation in regard to its safety.  Teflon, itself has not been proven to be harmful.  However, a key chemical used in its manufacturing process is perfluorooctanoic acid, which has been considered to be carcinogenic and may cause birth defects.  It is important to note that perfluorooctanoic acid is NOT found in Teflon(R).

YESH....it is absolutely SAFE!

Not only is it poisonous, but there is no reason that it should have any effect on the drugs in the urine. Chlorine will damage organs but not change drugs.

Be careful.\n\nThat environment can be dangerous.

I really doubt that they would take it back because there is a risk of contamination.  Take it to a pharmacy for disposal.

According to the COSHH (Control of Substances Hazardous to Health) their are several slight risks which are listed below\n(full COSHH included in sources)\n\n**Inhalation**\n Plaster dust may irritate respiratory\nsystem, no known long term effects.\n\n**Skin Contact**\nPlaster powder may dry skin, leading to\nirritation, if contact is prolonged or skin\nis sensitive.\n\nWet plasters or powders in contact with\nbody moisture may irritate as a low\nalkaline solution is produced.\n\n**Eye Contact**\n Plaster or wet mix splashes may irritate\nby particulate or alkalinity and must be\nwashed out immediately to reduce\nimmediate discomfort and any\npossibility of long term damage.\n\n**Ingestion**\nSmall amounts of plaster or wet mix\nshould not cause any significant reaction\nor long term effect.

Yes, because I have pets and their health is valuable to me, along with my own health and safety.  Not only that, we need more products that don't hurt the environment.  We don't need to be breathing chemicals in our houses.  I'm a cancer survivor and I'm a firm believer that environmental hazardous products cause about 90% of cancers, whether it be aluminium in deoderant to ammonia in cleaners.  I feel it breaks down the body's natural defenses to illness.
