10. Stability and Reactivity
Stability

Hazardous reactivity

Conditions to avoid: At first, vapor is generated by heating, and generate sulfuric
acid vapors if continue to heat.
Rapid contact with water might be generate a large amountof heat, and sometimes the acid is scattered.
Dilute sulfuric acid which is generated by diluting with water,
generates hydrogen gas by the corrosion of various metals
and may cause flash explosion by mixing with air.
There is hygroscopic.
: It may cause fire or explosion by many reactions.
It is strong oxidant and reacts with combustible andreducing materials.
It is strong acid and reacts violently with bases and iscorrosive to most common metals forming a
flammable/explosive gas (hydrogen).
React with water and organic materials violently and releaseheat.
: Generate irritating or toxic fumes or gases (sulfur oxides)

Skin corrosion/irritation

Serious eye damage/eye irritation

Respiratory or skin sensitization

Germ cell mutagenicity: Based on the Rat LD50 value: 2140mg/kg and the descriptionof the death case report by the oral ingestion in humans(amount of intake is unknown), it was classified as Category
5 (“Not classified” by JIS classification).
: No data.
: Classification not applicable because it is a liquid in thedefinition of GHS.
: No data.
: Based on rat LC50 value: 0.375mg/L (4 hour exposure) and
347ppm (1-hour exposure) (4 hour equivalent value:
0.347mg/L), it was classified as Category 2.
: Since pH of sulfuric acid was 1 or less, it was judged to becorrosive substance in accordance with the GHS
classification standards, and classified as Category 1A.
: There is the description that the critical damage to the eye
accompanied by lysis of anterior chamber of eye wasobserved in accident case of human. And also from thedescription that the moderate irritation with 5% solution andthe severe irritation with 10% solution were observed to theeye of rabbit, therefore, it was classified as "Category 1".
: Respiratory sensitization: No data.
Skin sensitization:
There is no test data on skin sensitizing of sulfuric acids.
Although sulfuric acid has been industrially used for several
decades, there is no case report of skin sensitization while
skin injuries by skin irritation are well known.
Although an extensive amount of sulfate ion exists
internally (the sulfate ion in serum ~33 mmol/L, and 50
times more in cells), allergic reactions do not occur.
In allergic test of sulfuric acid salt of metal, even if allergic
positive with metal may occur, sulfuric ion is presumed toresult in allergic negative as is suggested by the negative
results in sulfate of zinc. Based on the description that
conclusion is obtained from the results mentioned abovethat sulfate does not cause allergy to human, it wasclassified as "Not classified".
: For in vivo, there is not any test data which the reproductive

Reproductive toxicity

Specific target organ toxicity(single exposure)Specific target organ toxicity(repeated exposure)cells and the somatic cells were used. For in vitro
mutagenicity tests, there is the positive result only in the test
system with the single indicator (chromosomal aberrationtest). However, there are negative results in other indices.
Therefore, it was classified as "Classification not possible".
: Occupational exposure of the mist of the inorganic strongacid including sulfuric acids is classified as group 1
according to IARC, as A2 according to ACGIH, and as K
according to NTP.
Respect the evaluation of IARC and the latest NTP, it wasclassified as category 1. However, sulfuric acids itself wasclassified as the category 4 according to DFGOT. And, sincenone of those institutions have carried out the carcinogenic
classification, it was classified as "Classification notpossible".
: In inhalation exposure test using rabbit and mouse in fetalorganogenesis period, it is not observed of fetotoxicity andteratogenicity at the dose causing no maternal toxicity inboth species. And also, the effect on the reproductive organof both sexes is not observed in chronic toxicity test andcarcinogenicity test. Since the direct effect byirritation/corrosive is the main toxicity, it is judged that there
is no concern that indicates the reproductive toxicity,
therefore, it was classified as "Not classified".
: There is the descriptions that in the inhalation exposure of
low concentration in humans, airway irritation symptoms
such as cough and breath shortness are observed and athigh concentration exposure, addition to acute effects suchas cough, breathe shortness and hemoptysis shedding etc.,
permanent effects such as functional depression of lungs,
fibrosis and emphysema are observed. Additionally, there is
the description that hemorrhage and dysfunction in lungs
were observed in 8-hour inhalation exposure using guinea
pigs. Based on these descriptions, it was classified as"Category 1 (respiratory systems)".
: In the 28-day inhalation exposure test using rat, cellproliferation in laryngeal mucosa is observed in guidancevalue range of Category 1. In the 14 to 139-day repeatedinhalation exposure test using the guinea pigs, respiratory
and lung disorder, such as nasal-septum dropsy, pulmonary
emphysema, atelectasis, hyperemia, dropsy, bleeding andthrombosis of bronchioles are observed at the concentration
range of guidance value of Category 1. Furthermore, in the
78-week inhalation exposure test using a cynomolgus,
histological change as hyperplasia of a cell, the wall
thickening, etc. in bronchioles of lungs were observed at theProduct name: Dilute Sulfuric acid (Electrolyte for lead acid battery)

13. Precautions for Disposal
Residual wastes

Contaminated container and packages: Before disposal, to be the low level hazard state, performthe process of detoxification, stabilization and neutralizationand the like as much as possible.
Because it is a strong acid, dispose after neutralizing withan alkali.
In the disposal, follow the relevant laws and regulations andthe standards of the local government.
Entrust disposal to industrial waste disposal contractor who
has received the permission of prefectural governor, or if thelocal government is performing waste disposal, entrust themdisposal.
: Recycle containers after cleaning up or dispose of properlyin accordance with relevant laws and local regulations.
If dispose the empty container, dispose after removing
contents completely.
