•Contamination prevention
•Hazard elimination
Level 2: Administrative Controls
•Work practice procedures
•Safe cleanup protocols
•Training programs
•Medical surveillance
•Exposure reporting
Level 3: Personal Protective Equipment
•N95 respirators
•Gloves
•Eye protection
•Gowns/clothing
•Proper donning/doffing
High-Risk Work Procedures
Grain Handling Safety
1.N95 respirator always in grain areas
2.Check for rodent signs before work
3.Proper ventilation running
4.Don't eat in work areas
5.Hand washing before meals
6.Glove use mandatory
7.Report signs of infestation
Building Contamination Cleanup
1.Inspect before entry
2.Assess contamination level
3.Full PPE requirements
4.Proper ventilation setup
5.Damp cleaning only (no sweeping)
6.Bleach solution for disinfection
7.Sealed disposal of materials
8.Post-cleanup documentation
Old Building/Shelter Use
1.Inspect structure before use
2.Look for rodent signs
3.Proper ventilation
4.Seal obvious entry points
5.Don't touch droppings
6.Food storage away from structure
7.Hand hygiene enforcement
Medical Surveillance Programs
For High-Risk Workers
•Baseline health assessment
•Symptom monitoring education
•Quick access to medical care
•Post-exposure protocols
•Regular check-ins
Fever Tracking
•Any fever during work = medical attention
•Respiratory symptoms = immediate care
•Occupational history documented

What Workers Should Know
1.Your occupational risk: Know if your job is high-risk
2.Symptoms: Recognize fever + myalgia + respiratory symptoms
3.Medical access: Know where to seek care
4.Reporting: Report exposures and symptoms
5.Prevention: Use PPE correctly
6.Training: Participate in safety training
The Bottom Line
Many occupations carry hantavirus risk, but risk can be managed through:
•Proper engineering controls
•Correct PPE use
•Safe procedures
•Medical awareness
•Early reporting
If your occupation exposes you to hantavirus risk, understand that risk, use proper protection, and seek immediate medical attention for any symptoms.
