Potential Health Effects
----------------------------------
This material is relatively nonhazardous in routine industrial situations.
Inhalation: No adverse health effects expected from inhalation. May cause
a short period of rapid or difficult breathing.
Ingestion: A burning sensation of the mouth may be noted following
ingestion of methylene blue. May cause nausea, vomiting, diarrhea, and
gastritis. Large doses may cause abdominal and chest pain, headache, profuse
sweating, mental confusion, painful micturation, and methemoglobinemia.
Skin Contact:Not expected to be a health hazard from skin exposure.
Methylene blue may color the skin a bluish color. May cause photosensitization.
Eye Contact:No adverse effects expected. May cause mechanical irritation.
Chronic Exposure:No information found.
Aggravation of Pre-existing Conditions:No information found.
Inhalation:Remove to fresh air. Get medical
attention for any breathing difficulty.
Ingestion:Induce vomiting immediately as directed by medical personnel.
Never give anything by mouth to an unconscious person.
Skin Contact:Immediately flush skin with plenty of soap and water for at
least 15 minutes. Remove contaminated clothing and shoes. Wash clothing before
reuse. Thoroughly clean shoes before reuse. Get medical attention if irritation
develops.
Eye Contact:Immediately flush eyes with plenty of water for at least 15
minutes, lifting upper and lower eyelids occasionally. Get medical attention if
irritation persists.
Fire:Methylene blue does not burn. Not considered to
be a fire hazard.
Explosion:Not considered to be an explosion hazard.
Fire Extinguishing Media:Use any means suitable for extinguishing
surrounding fire.
Special Information:In the event of a fire, wear full protective clothing
and NIOSH-approved self-contained breathing apparatus with full facepiece
operated in the pressure demand or other positive pressure mode.
Ventilate area of leak or spill. Wear appropriate personal
protective equipment as specified in Section 8. Spills: Pick up and place in a
suitable container for reclamation or disposal, using a method that does not
generate dust.
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Avoid dust formation and control ignition sources. Isolate from incompatible substances. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.
Airborne Exposure Limits: None established.
Ventilation System:In general, dilution ventilation is a satisfactory
health hazard control for this substance. However, if conditions of use create
discomfort to the worker, a local exhaust system should be considered.
Personal Respirators (NIOSH Approved):
Not expected to require personal respirator usage. For conditions of use where
exposure to dust or mist is apparent and engineering controls are not feasible,
a particulate respirator (NIOSH type N95 or better filters) may be worn. If oil
particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present, use a
NIOSH type R or P filter. For emergencies or instances where the exposure levels
are not known, use a full-face positive-pressure, air-supplied respirator.
WARNING: Air-purifying respirators do not protect workers in oxygen-deficient
atmospheres.
Skin Protection:Wear protective gloves and clean body-covering clothing.
Eye Protection:Use chemical safety goggles and/or full face shield where
dusting or splashing of solutions is possible. Maintain eye wash fountain and
quick-drench facilities in work area.
Appearance: Dark green crystals with bronze luster
or crystalline powder.
Odor: Odorless.
Solubility: Soluble in water.
Specific Gravity: No information found.
pH: No information found.
% Volatiles by volume @ 21C (70F): 0
Boiling Point: Decomposes.
Melting Point: 100 - 110C (212 - 230F)
Vapor Density (Air=1): 13
Vapor Pressure (mm Hg): Not applicable.
Evaporation Rate (BuAc=1): No information found.
Stability:
Stable under ordinary conditions of use and storage.
Hazardous Decomposition Products:
May produce oxides of nitrogen, sulfur and carbon when heated to decomposition.
Hazardous Polymerization: Will not occur.
Incompatibilities: Strong oxidizing agents, alkali, dichromates, alkali
iodides, reducing agents.
Conditions to Avoid: Heat, flame, ignition sources, dusting and
incompatibles.
Environmental Fate:When released into the soil, this
material is not expected to evaporate significantly. When released into water,
this material is not expected to evaporate significantly. This material has an
estimated bioconcentration factor (BCF) of less than 100. This material is not
expected to significantly bioaccumulate. When released into the air, this
material is expected to be readily degraded by reaction with photochemically
produced hydroxyl radicals. When released into the air, this material may be
removed from the atmosphere to a moderate extent by wet deposition. When
released into the air, this material may be removed from the atmosphere to a
moderate extent by dry deposition.
Environmental Toxicity:No information found.
Whatever cannot be saved for recovery or recycling should be managed in an appropriate and approved waste disposal facility. Processing, use or contamination of this product may change the waste management options. State and local disposal regulations may differ from federal disposal regulations. Dispose of container and unused contents in accordance with federal, state and local requirements.
