Remove victim to fresh air and keep at rest in a position comfortable
for breathing. If it is suspected that fumes are still present, the rescuer
should wear an appropriate mask or self-contained breathing
apparatus. If not breathing, if breathing is irregular or if respiratory
arrest occurs, provide artificial respiration or oxygen by trained
personnel. It may be dangerous to the person providing aid to give
mouth-to-mouth resuscitation. If unconscious, place in recovery
position and get medical attention immediately. Maintain an open
airway. Loosen tight clothing such as a collar, tie, belt or waistband. In
case of inhalation of decomposition products in a fire, symptoms may
be delayed. The exposed person may need to be kept under medical
surveillance for 48 hours.
Skin contact : Get medical attention immediately. Call a poison center or physician.
Wash with plenty of soap and water. Remove contaminated clothing
and shoes. Wash contaminated clothing thoroughly with water before
removing it, or wear gloves. Continue to rinse for at least 10 minutes.
Chemical burns must be treated promptly by a physician. In the event
of any complaints or symptoms, avoid further exposure. Wash clothing
before reuse. Clean shoes thoroughly before reuse.
Ingestion : Get medical attention immediately. Call a poison center or physician.
Wash out mouth with water. Remove dentures if any. Remove victim
to fresh air and keep at rest in a position comfortable for breathing. If
material has been swallowed and the exposed person is conscious, give
small quantities of water to drink. Stop if the exposed person feels sick
as vomiting may be dangerous. Do not induce vomiting unless directed
to do so by medical personnel. If vomiting occurs, the head should be
kept low so that vomit does not enter the lungs. Chemical burns must
be treated promptly by a physician. Never give anything by mouth to
an unconscious person. If unconscious, place in recovery position and
get medical attention immediately. Maintain an open airway. Loosen
tight clothing such as a collar, tie, belt or waistband.

Version: 3.2 Date of issue/Date of revision: 07/31/2019 Date of previous issue: 02/24/2017
national guidance documents for methods for the determination of
hazardous substances will also be required.
Appropriate engineering controls : Use only with adequate ventilation. If user operations generate dust,
fumes, gas, vapor or mist, use process enclosures, local exhaust
ventilation or other engineering controls to keep worker exposure to
airborne contaminants below any recommended or statutory limits.
Environmental exposure controls : Emissions from ventilation or work process equipment should be
checked to ensure 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. Contaminated work
clothing should not be allowed out of the workplace. Wash
contaminated clothing before reusing. Ensure that eyewash stations
and safety showers are close to the workstation location.
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 and/or face
shield. If inhalation hazards exist, a full-face respirator may be
required instead.
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.
Other skin protection : Appropriate footwear and any additional skin protection measures
should be selected based on the task being performed and the risks
involved and should be approved by a specialist before handling this
product.
Respiratory protection : Use a properly fitted, air-purifying or air-fed respirator complying with
an approved standard if a risk assessment indicates this is necessary.
