4. First Aid Measures
Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give
oxygen. Get medical attention.
Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to
an unconscious person. Get medical attention.
Immediately flush skin with plenty of water for at least 15 minutes. Remove contaminated
clothing and shoes. Get medical attention. Wash clothing before reuse. Thoroughly clean shoes
Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper
eyelids occasionally. Get medical attention immediately.
5. Fire Fighting Measures
Not considered to be a fire hazard.
Not considered to be an explosion hazard. Dry Glyoxal may explode when mixed with air.
Fire Extinguishing Media:
Use any means suitable for extinguishing surrounding fire.
In the event of a fire, wear full protective clothing and NIOSH .approved self .contained
breathing apparatus with full face piece operated in the pressure demand or other positive
6. Accidental Release Measures
Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8. Contain and
recover liquid when possible. Collect liquid in an appropriate container or absorb with an inert material (e. g.,
vermiculite, dry sand, earth), and place in a chemical waste container. Do not use combustible materials, such as saw
dust. Do not flush to sewer !
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Isolate from
incompatible substances. Containers of this material may be hazardous when empty since they retain product residues
(vapors, liquid); observe all warnings and precautions listed for the product.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
Glyoxal, vapor and aerosol, inhalable fraction:
ACGIH Threshold Limit Value (TLV): 0.1 mg/m3 SEN, A4. Not classifiable as a human
A system of local and/or general exhaust is recommended to keep employee exposures below the
Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control
the emissions of the contaminant at its source, preventing dispersion of it into the general work
Personal Respirators (NIOSH Approved):
For conditions of use where exposure to the substance is apparent and engineering controls are
not feasible, consult an industrial hygienist. For emergencies, or instances where the exposure
levels are not known, use a full.facepiece positive. Pressure, air supplied respirator. WARNING:
Air purifying respirators do not protect workers in oxygen deficient atmospheres.
Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as
appropriate, to prevent skin contact.
Use chemical safety goggles and/or a full face shield where splashing is possible. Maintain eye
wash fountain and quick. drench facilities in work area.

10. Stability and Reactivity
Stable under ordinary conditions of use and storage.
Hazardous Decomposition Products:
Carbon dioxide and carbon monoxide may form when heated to decomposition.
Peroxide formation not expected in the presence of inhibitors. Dry Glyoxal polymerizes quickly
on standing, on contact with water (violent reaction), or solvents containing water.
Reacts weakly to acids. Incompatible with strong oxidizing agents, strong bases, silver, copper
and iron salts. Corrosive to most metals.
Conditions to Avoid:
Heat, flames, ignition sources and incompatibles.
