bronchospasm), hemoptysis (early symptoms of poisoning). Effects
may be delayed (up to 48 hrs) and may lead to toxic pulmonary edema.
Ingestion
Ingestion of small amounts of nitric acid adversely affects the mouth,
throat, larynx, esophagus and gastrointestinal tract. Ingestion may lead
to nausea, vomiting, swelling of larynx and possible "coffee grounds"
appearance of the vomitus. May be fatal if swallowed.
Skin contact
Corrosive to the skin.
Eye contact
Causes serious eye damage.
Delayed and immediate effects as well as chronic effects from short and long-term exposure
Acute toxicity of nitric acid is specific due to delayed clinical signs of exposure to nitric acid. Usually three steps
are considered. The first one is characterized by irritation of mucous membranes of nose and throat, dyspnea,
coughing and general malaise. In the second step the symptoms mentioned hereinabove are almost gone and
this can last up to several dozen of ours. After this period, there may be a relapse that stars with sudden
occurrence of clinical symptoms. Patients are suffering from paroxysmal cough, nausea and vomiting. Fever and
the blood pressure decrease are also observed. Death may occur. Long-term exposure may lead to chronic
gingivitis and laryngitis, headache, sleeping disorders and weakness.

9. Technical conditions and measures to prevent or avoid human exposure
In general, production considers tasks and activities, which are performed continuously in closed system. During
normal operation, the reactor is closed therefore no likelihood of exposure to nitric acid vapours.
Use local exhaust and general mechanical ventilation.
10. Conditions and measures related to personal protection, hygiene and health evaluation
Workers may be occasionally exposed to nitric acid by inhalation and dermal contact (e.g. sample collection or
accident).
The frequency and duration of exposure vary considerably, depending on scheduled tasks. In some cases
elevated short-term exposure may arise, therefore additional risk management measures must be taken into
account (e.g. personal protective equipment).
Eye protection
If exposure to aerosols exists, wear safety glasses according to EN 166
standard or face mask in line with EN 402 standard.
Skin and body protection
Use acid resistant protective clothing and rubber boots.
Hand protection
In case of dermal contact, use impermeable chemical resistant protective
gloves complying with EN 374 standard (obligatory), made of butyl rubber,
PVC, Teflon, fluoroelastomer.
Respiratory protection
Short exposure periods: use masks in line with EN 149 standard type FF P3 or
EN 14387 type B or P3 E, EN 1827 class FMP3
Long term exposure: protective mask according with EN 143, EN 14387, EN
12083 class P3 or XP3, EN 12941 class TH3, EN 12942 TM3, EN 14593 or

Personnel dealing with possibility of exposure to nitric acid should be trained
on:
Other recommended protection
measures
•
use of personal protective equipment (especially respiratory protection)
•
potential risk ( especially corrosive influence to skin and respiratory
system) resulting from contact with nitric acid
•
adherence to safety measures and standard operating procedures
The Employee is obliged to control availability and usage of required personal
protective equipment.
11. Frequency and duration of environmental release
A combination of organizational and technical measures (leak detection and control) should be implemented to
eliminate unexpected release.
12. Technical conditions and measures to reduce or avoid environmental release
Regular checks of pH values are required when discharging into open waters. In general, waste should be
discharged so that it minimises any change in the pH of the surface waters where it is to be disposed of (maintain
pH for industrial discharges in the range of 6-9).
NOTE:
The natural pH and buffer capacity of open waters can vary significantly between different aquatic ecosystems.
Nitric acid gradually dissociates in water (HNO3 = H+ + NO3- (pKa= -1.4)) by affecting the pH of the water,
depending on its buffer capacity. This may have toxic effects to aquatic organisms (fish, algae, crustaceans)
which are able to adapt to pH change in the range of 6-9.

9. Technical conditions and measures to prevent or avoid human exposure
Due to corrosive properties of nitric acid, risk management measures (RMM) should be focused on preventing
from direct contact with the substance. Therefore industrial manufacture and use of nitric acid should be carried
out in closed automated systems.
Closed automated systems are not feasible in case of applications dealing with low concentrated nitric acid
solutions. In this event direct contact with nitric acid is limited by the use of personal protective equipment.
Use local exhaust and general mechanical ventilation.
