Acute toxicity (oral)
Acute toxicity (dermal)
Acute toxicity (inhalation): Harmful if swallowed
rat LD50=238-277mg/kg (as hydrogen chloride): No classification
rabbit LD50>5010mg/kg (as hydrogen chloride): No classification (gas)Classification not possible (vapor)Harmful if inhaled: rat LC50=0.42mg/L/4h (as hydrogen chloride)

Acute toxicity (mist) Description
Skin corrosion/irritation:

Serious eye damage/irritation:

Respiratory sensitization:

Skin sensitization:

Germ cell mutagenicity:

Carcinogenicity:

Causes severe skin burns
In a rabbit skin irritation test, application for 1 - 4-hour caused
corrosion at higher concentrations. Skin irritation and ulceration
with fur discoloration occurred in mice and rats dermally exposedfor 5 - 30 minutes. In human experiments, there are reports that
contact caused slight to strong irritation, or ulceration andsevere burns to the skin. Based on these data, the substance wasconsidered to have corrosive properties, and was classified into
category 1B.
Causes serious eye damage
The substance was classified as a skin corrosive substance. In eye
damage and irritation tests, solutions of the substance,hydrochloric acid, was used as a test substance. In animal tests
including rabbit tests, high irritation, damage and corrosion toeyes have been reported. For humans, the concentrated solution cancause permanent damage and loss of sight. Based on these data, thesubstance was classified into category 1.
May cause allergy or asthma symptoms or breathing difficulties if
inhaled.
Since the substance is on the sensitizing chemical substance list
by Japanese Society of Occupational and Environmental allergy, thesubstance was classified into category 1. There is a report thatafter exposure to a cleaning product that contained hydrogenchloride, the subject developed bronchospasm and still had marked
asthma symptoms 1 year after exposure that were triggered byexercise and inhalation of trivial concentrations of irritants.
No classification
A guinea pig maximization test and a mouse ear swelling test
demonstrated negative results for the substance. In a human test
using fifty volunteers, none gave a positive reaction in achallenge application, 10 - 14 days after the final induction
application. The substance was classified as "No classification".
Classification not possible
Classification not possible due to lack of data from in vivo
mutagenicity tests. From in vitro mutagenicity tests, there is areport of a negative Ames test and a positive result (which isconsidered to be an artifact due to the low pH) chromosome
aberration test.
No classification
IARC classifies IARC classifies hydrochloric acid as group 3 (notclassifiable as to its carcinogenicity to humans).

Reproductive toxicity:

STOT-single exposure:

STOT-repeated exposure:

Aspiration hazard:

Classification not possible
In rat and mice tests by exposure during gestation period, there
were no adverse effects on fetal development, however,classification was not possible since there are no data for effects
on sexual function and fertility by exposure before mating or
gestation.
Causes damage to organs (respiratory organs)In humans, inhalation exposure caused symptoms such as dyspnea,
laryngitis, bronchitis, bronchoconstriction, pneumonia and edema.
Inflammation and necrosis of the upper respiratory tract andpulmonary edema have also been reported. In animal tests, toxic
effects with morphological change of the lung and bronchus such asbronchitis with mucosal necrosis, pulmonary edema, hemorrhage, andthrombus were observed at dose levels within the guidance value
range for category 1. Based on the information for humans andanimals, the substance was classified into category 1 (respiratoryorgans).
Causes damage to organs (teeth, respiratory organs) throughprolonged or repeated exposure
There are 2 or more reports for humans in which repeated exposure
caused tooth damage by erosion. Additionally, an increase in thefrequency of chronic bronchitis was reported. Based on theinformation, the substance was classified into category 1 (teeth,
respiratory organs).
Classification not possible

12. Ecological information
Ecotoxicity
Aquatic acute
Aquatic chronic: Very toxic to aquatic life
Daphnia magna EC50=0.492mg/L/48h (as hydrogen chloride): No classification
Classified into "No classification" since the toxicity is
mitigated in environmental water by buffer action though it isconsidered to be a factor of toxicity that water solution becomesstrongly acidic.

Persistence and degradability
No additional information available
Bioaccumulative potential
No additional information available
Mobility in soil
No additional information available
Hazardous to the ozone layer
Ozone: Classification not possible

13. Disposal considerations
Ecological waste information: Neutralization method :After gradually adding to a stirring solution such as lime
milk to neutralize, dilute with a large amount of water fortreatment.
