TWA : 10 ppm 8 hours . 1 -Methoxy-2- propanol NOM -010 -STPS -2014 ( Mexico , 4/2016) . STEL : 150 ppm 15 minutes . TWA : 100 ppm 8 hours . ethanol NOM -010 -STPS -2014 ( Mexico , 4/2016 ) . STEL : 1000 ppm 15 minutes . Methyl n -Amyl Ketone NOM -010 -STPS -2014 ( Mexico , 4/2016) . TWA : 50 ppm 8 hours . 2 - Methoxymethyl ethoxypropanol NOM -010 -STPS -2014 ( Mexico , 4/2016 ) . Absorbed through skin . TWA : 100 ppm 8 hours . STEL : 150 ppm 15 minutes . Appropriate engineering Use only with adequate ventilation . Use process enclosures , local exhaust ventilation or controls other engineering controls to keep worker exposure to airborne contaminants below any recommended or statutory limits . The engineering controls also need to keep gas , vapor or dust concentrations below any lower explosive limits . Use explosion - proof ventilation equipment . Environmental exposure Emissions from ventilation or work process equipment should be checked to ensure controls they comply with the requirements of environmental protection legislation . In some cases , fume scrubbers , filters or engineering modifications to the process equipment will be necessary to reduce emissions to acceptable levels . Individual protection measures Hygiene measures Wash hands , forearms and face thoroughly after handling chemical products , before eating , smoking and using the lavatory and at the end of the working period . Appropriate techniques should be used to remove potentially contaminated clothing . Wash contaminated clothing before reusing .

Eye/face protection Safety eyewear complying with an approved standard should be used when a risk assessment indicates this is necessary to avoid exposure to liquid splashes , mists , gases or dusts . If contact is possible , the following protection should be worn , unless the assessment indicates a higher degree of protection : chemical splash goggles . Skin protection Hand protection Chemical - resistant, impervious gloves complying with an approved standard should be worn at all times when handling chemical products if a risk assessment indicates this is necessary. Considering the parameters specified by the glove manufacturer, check during use that the gloves are still retaining their protective properties . It should be noted that the time to breakthrough for any glove material may be different for different glove manufacturers . In the case of mixtures , consisting of several substances , the protection time of the gloves cannot be accurately estimated . Body protection Personal protective equipment for the body should be selected based on the task being performed and the risks involved and should be approved by a specialist before handling this product . When there is a risk of ignition from static electricity, wear antk static protective clothing .
