Perhaps the party under the most pressure with the changes then is the chemical manufacturers, who are required to replace their existing product labels with ones that embrace the new format.

“Manufacturers have a lot of latitude in how they make [chemical label] descriptions but with the new standard it is much more prescriptive,” says Bill Balek, director of legislative affairs at the ISSA. “Before they re-label they have to reclassify their products. We’re using a different scheme of stratifying the products and they are very detailed.” 

Besides changing labels, the revised safety data sheets require information to be presented in a 16-section sequence. Before GHS, OSHA allowed either its eight-section format or ANSI’s 16-section format to be used. Now, the SDS will be similar to ANSI’s version with the requirement that the sections be presented in a strict order. Formerly, the document’s format was left up to manufacturers. 

The required order is as follows: Identification, Hazard’s identification, Composition/information on ingredients, First Aid measures, Fire-fighting measures, Handling and Storage, Exposure controls/personal protection, Physical and chemical properties, Stability and reactivity, Toxicological information, Ecological information, Disposal considerations, Transport information, Regulatory information, and Other information, including date of preparation or last revision. 

Casavant expects the changes to SDSs and chemical labels to present an ongoing challenge to employers, as they attempt to bring their inventory into compliance.

“I think it’s safe to say that folks are stressed,” he says. “People are quite concerned about the workload this new standard will bring. [Employers] suspect some chemical manufacturers will take their time in complying and that will create issues for end users downstream.”

GREEN CHEMICALS

The Green Seal certification is granted by the organization with that name and has a great number of members contributing with the requirements to pass a raw material or a chemical product as "green". Generally for a material to be green, has to comply with a series of characteristics like: near neutral pH, low volatility, non combustible, non toxic to aquatic life, be biodegradable as measured by oxygen demand in accordance with the OECD definition.
Also the materials have to meet with toxicity and health requirements regarding inhalation, dermal and eye contact. There is also a specific list of materials that are prohibited or restricted from formulations, like ozone-depleting compounds and alkylphenol ethoxylates amongst others. Please go to http://www.greenseal.com/ for complete information on their requirements.
For information on current issues regarding green chemicals, see the blog from the Journalist Doris De Guzman, in the ICIS at: http://www.icis.com/blogs/green-chemicals/.
Certification is an important — and confusing — aspect of green cleaning. Third-party certification is available for products that meet standards set by Green Seal, EcoLogo, Energy Star, the Carpet & Rug Institute and others.
Manufacturers can also hire independent labs to determine whether a product is environmentally preferable and then place the manufacturer’s own eco-logo on the product; this is called self-certification. Finally, some manufacturers label a product with words like “sustainable,” “green,” or “earth friendly” without any third-party verification.
“The fact that there is not a single authoritative standard to go by adds to the confusion,” says Steven L. Mack M.Ed., director of buildings and grounds service for Ohio University, Athens, Ohio.
In www.happi.com of June 2008 edition, there is a report of Natural formulating markets that also emphasises the fact that registration of "green formulas" is very confused at present, due to lack of direction and unification of criteria and that some governmental instittion (in my opinion the EPA) should take part in this very important issue.
