H335

Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.

|Warning|H335: May cause respiratory irritation [Warning Specific target organ toxicity, single exposure; Respiratory tract irritation]|P261, P271, P304+P340, P312, P403+P233, P405, and P501

In case of fire in the surroundings, use appropriate extinguishing media.

Skin: No recommendation is made specifying the need for personal protective equipment for the body. Eyes: No recommendation is made specifying the need for eye protection. Wash skin: No recommendation is made specifying the need for washing the substance from the skin (either immediately or at the end of the work shift). Remove: No recommendation is made specifying the need for removing clothing that becomes wet or contaminated. Change: No recommendation is made specifying the need for the worker to change clothing after the work shift. (NIOSH, 2016)|(See protection codes)

Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into containers. If appropriate, moisten first to prevent dusting.

A nuisance-causing concentration of airborne particles can be reached quickly when dispersed.

May cause mechanical irritation.

Lungs may be affected by repeated or prolongated exposure to dust particles.

Use local exhaust or breathing protection.

Wear safety spectacles.

Materials used in the production of dental bases, restorations, impressions, prostheses, etc. (See all compounds classified as Dental Materials.)

Exposure Routes: inhalation, skin and/or eye contact Symptoms: Irritation eyes, skin, mucous membrane, upper respiratory system; cough, sneezing, rhinorrhea (discharge of thin mucus) Target Organs: Eyes, skin, respiratory system (NIOSH, 2016)

Eye: If this chemical contacts the eyes, immediately wash the eyes with large amounts of water, occasionally lifting the lower and upper lids. Get medical attention immediately. Contact lenses should not be worn when working with this chemical. Breathing: If a person breathes large amounts of this chemical, move the exposed person to fresh air at once. Other measures are usually unnecessary. (NIOSH, 2016)|(See procedures)

Fresh air, rest.

Rinse and then wash skin with water and soap.

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
