Due to its corrosive and reactive properties, nitric acid (HNO3) should be handled and kept carefully.

Some safe handling and storage guidelines for nitric acid are provided below:

Managing Nitric Acid (HNO3)Use:

Accessories for Personal Protection (PPE):

1. Wear the appropriate safety gear, such as a face shield, goggles, and gloves resistant to acid.
2. Put on boots that can withstand acids in addition to aprons to minimize skin contact.

Ventilation:

1. For reduced inhalation exposure, work in an area with good ventilation or utilize a fume hood.
2. Use a respirator if necessary, to protect your lungs from vapor inhalation.

Handling Procedures:

1. Take care whilst handling nitric acid avoiding splashes or spills.
2. When adding water into acid, always rather than the other way around so as to prevent violent reactions from occurring
3. Put away the metals since they can react with nitric acid, instead utilize plastics or glasses in case

Emergency Equipment:

In case one has got contact with the above substance accidentally locate an eyewash station or an emergency shower immediately.

Training:

Ensure that personnel are adequately trained in how to handle nitric acid safely. In addition, ensure employees get familiarized with first aid measures and emergency procedures.

Storage of Nitric Acid:

Storage Container:

Do not store Nitric Acid in metal containers as it might corrode them but those made of high-density polyethylene (HDPE) or glass ones are ideal enough.

Labeling:

Clearly label storage containers with the chemical name, concentration, and any hazards associated with nitric acid. Let this be done meticulously

Separation:

Separate nitric acid from such incompatible things like organic materials, reducing agents and strong bases among others

Ventilation:

The ventilation system should be able to disperse any fumes released by stored items especially when these have been ionised into different gases

Temperature Control:

Keep away from heat sources and direct sunlight where there is no overheating possibility or decomposition

HNO3: Molecular Structure

Secondary Containment:

Use trays or basins designed to contain any spills that could occur as a result of punctured primary storage systems.

Regular Inspections:

Inspect storage containers regularly for signs of damage or deterioration.

Emergency Response:

Spill Response:

Wear the appropriate protective gear while neutralizing any small spills with a proper base like NaHCO3.

Emergency Contacts:

Make sure you have emergency contact numbers for medical assistance and hazardous material response.

First Aid:

Ensure that there is a first aid box which is equipped with necessary materials for acid exposure treatment, moreover ensure employees are trained on first aid procedures.

By following these best practices, you can minimize the risks associated with handling and storing nitric acid, thus creating a safer working environment. Additionally, always consult local regulations and guidelines for additional specific requirements in your area.
