Clear Signage: Your First Line of Defense

Proper signage is a basic yet crucial OSHA requirement. It serves multiple functions: alerting tenants to hazards, directing traffic, and providing emergency contact information.

What to include:

• Danger and warning signs near work areas
• Temporary exit and route markers if pathways are altered
• Contact numbers for site supervisors or emergency services

OSHA's guidelines 29 CFR 1926.200 specify how construction signs should be designed and placed.

Best Practice: Use bilingual or multilingual signage if your tenant population is diverse.

Physical Barriers: Separating Construction from Daily Operations

OSHA requires clear separation between active construction zones and occupied areas. Physical barriers help minimize risk and liability by keeping unauthorized individuals out.

Common solutions include:

• Temporary walls (polycarbonate or drywall)
• Zip-wall systems
• Lockable access doors

These not only maintain OSHA compliance but also support fire safety and reduce disruptions to tenant operations.

Dust Containment: Protecting Air Quality and Health

Construction dust isn't just a nuisance; it can pose serious health hazards. OSHA's standard for respiratory protection (29 CFR 1910.134) requires employers to limit exposure to airborne particles.

Methods for effective dust control:

• HEPA-filtered negative air machines
• Containment tents for localized demolition
• Sticky mats and sealed ductwork

You’ll also want to monitor air quality regularly and document those reports to stay compliant.

Noise Control: Minimizing Disturbance While Staying Productive

Noise can be more than just annoying—it can impact productivity and health. OSHA limits workplace noise exposure to 90 dB over an 8-hour shift (29 CFR 1910.95). In tenant construction, it's just as important to minimize disruption.

Effective strategies:

• Scheduling high-noise work during off-hours
• Installing acoustic curtains or barriers
• Using quieter equipment models or electric alternatives

Providing tenants with a noise calendar can also improve satisfaction and reduce complaints.

Scheduling and Working Hours: Coordinating Around Occupants

While OSHA does not mandate specific work hours, coordinating construction schedules to accommodate tenant needs is a best practice that supports safety and compliance.

Tips for schedule management:

• Prioritize high-disruption tasks outside of business hours
• Use phased work zones to limit occupied area disruptions
• Communicate schedules well in advance with all stakeholders

This also reduces the risk of accidents caused by unexpected tenant foot traffic through active work zones.
