Employer Responsibilities and Legal Requirements

Workplace earthquake preparedness exists within a legal framework that assigns clear responsibilities to employers in seismically active regions. The Occupational Safety and Health Administration (OSHA) General Duty Clause requires employers to provide a workplace free from recognized hazards likely to cause serious physical harm, which courts and regulatory agencies have interpreted to include earthquake preparedness for workplaces in high-seismic zones. Cal/OSHA and similar state agencies have more specific requirements in high-risk states, including emergency action plans, evacuation drills, and first aid training.

OSHA standard 29 CFR 1910.38 requires employers with more than ten employees to maintain a written emergency action plan that addresses fire, but virtually all emergency management authorities recommend extending this plan to include earthquake scenarios. A compliant earthquake emergency action plan includes: evacuation routes with designated assembly areas, procedures for employees with disabilities who may need evacuation assistance, a designated coordinator responsible for accounting for all employees after an evacuation, and procedures for shutting off utilities and critical equipment.

Buildings constructed before jurisdiction-specific seismic design provisions were adopted may be subject to mandatory retrofit programs; employers should verify whether their building is in compliance with current ordinances and obtain a structural engineer's assessment if the building's seismic history is unclear. 无筋砌体未配置钢筋加固的砖石或砌块结构，对地震震动极为脆弱。无筋砌体建筑是全球地震死亡人数中占比最高的建筑类型。 and older tilt-up concrete construction are the highest-risk common commercial building types.

Office Drop Cover Hold Procedures

The 就地、掩护、抓牢地震震动期间国际公认的防护行动：双手双膝着地，躲到坚固家具下方掩护，并抓牢直至震动停止。 technique for office workers follows the same fundamental principles as residential application, with procedural adaptations for the office environment. When shaking begins, employees should immediately drop under their desks if a desk is within one or two steps, pulling themselves as far under the desk as possible and holding on to a desk leg. Monitors, desktop equipment, and desk accessories will shift and may fall; the desk surface provides critical protection.

Employees working at standing desks should drop to the ground and cover their head and neck with their arms, moving toward an interior wall or structural column if available. Open-plan offices with no nearby desk cover should direct employees to interior walls, away from glass partitions and window walls.

Reception areas, lobbies, and glass-fronted storefronts present elevated glass hazard risk. If your organization occupies a ground-floor space with a glass storefront, identify cover locations away from the glass line for all staff positions. After shaking stops, apply the same systematic assessment protocol used in residential settings: check for injuries, smell for gas, assess structural indicators before moving through the space, and use the Building Safety Checker framework to evaluate visible damage.

Evacuation Plans and Assembly Points

Effective evacuation planning begins with a floor plan that marks all primary and secondary exit routes, stairwells, fire exits, and assembly points. Post this plan in each office area and ensure that all employees are familiar with it through mandatory orientation for new hires and annual refreshers for existing staff. Exit routes in earthquake evacuation differ from fire evacuation in one critical respect: do not evacuate during shaking. Stairwells and corridors become extremely dangerous when ground motion causes people to lose footing, and exits blocked by falling debris present hazards that cannot be seen until the dust settles.

Designate two outdoor assembly points at distance from the building — typically one and a half building heights from the nearest exterior wall — where employees gather after shaking stops and evacuation is complete. Assembly points should be on open ground away from overhead utilities, adjacent structures, and underground utility corridors (which may have surface manifestations after rupture). A primary assembly point should be visible from the building exit; a secondary point is used if the primary is inaccessible.

Assign floor wardens or area coordinators responsible for conducting headcounts at assembly points, reporting missing persons to the emergency coordinator, and communicating with first responders. The floor warden role requires training and regular drill participation to be effective under the cognitive load of a real emergency. Include a protocol for accounting for visitors, contractors, and delivery personnel who may be in the building at the time of an earthquake and who are not on the standard employee roster.

Emergency Kit for the Office

An office-level 地震应急包为应对地震后生存需要而预先准备的物资集合，通常包括水（每人每天1加仑，供3天使用）、食物、急救用品、手电筒和收音机。 serves as a bridge between the immediate post-earthquake period and the arrival of professional emergency services or the safe return of employees to their homes. The minimum recommended content for a 25-person office includes: 75 gallons of water (one gallon per person per day, three-day supply), 150 pounds of non-perishable food, a first aid kit rated for 25 people (including at least two tourniquets and a CPR mask), a battery-powered NOAA radio, work gloves and dust masks for all staff, and a flashlight with spare batteries for every five employees.

Store office emergency supplies in a designated location known to all employees — typically a storage room on the ground floor with a non-glass door that can be accessed after structural disruption. Cabinet contents should be secured against toppling with positive-latch hardware. Water supplies stored in 55-gallon drums are space-efficient and eliminate the rotation burden of commercial bottled water, but require a manual siphon pump for dispensing.

Prescription medications are a critical gap in most office emergency supply inventories. Encourage employees to maintain a 48-hour supply of critical medications at their workstation in a labeled container, in addition to the office-level first aid supplies. This is particularly important for employees with insulin-dependent diabetes, seizure disorders, cardiac conditions, or psychiatric medications that require strict adherence schedules. Discuss this practice with HR to ensure compliance with medication policy while meeting safety needs.

Business Continuity After an Earthquake

Business continuity planning for earthquakes extends beyond physical safety to include data protection, vendor relationship management, remote work capability, and financial resilience. A business that survives a physical earthquake but loses critical data, customer relationships, or operational capacity due to infrastructure disruption may face a more severe long-term threat than the physical damage alone. 地震保险专门承保地震造成损失的保险，通常需与标准房屋保险分开单独购买，在日本、土耳其等一些国家属于强制险种。 for commercial properties typically covers physical structure and equipment but may not cover business interruption losses; review your coverage with your broker before an event.

Data backup and cloud infrastructure redundancy are the highest-leverage continuity investments for most businesses. Critical business data stored exclusively on on-premises servers can be destroyed or made inaccessible by earthquake-related power outages, water damage, or building condemnation. Cloud-based backups with daily or hourly snapshots, stored in geographically distributed data centers, ensure that data remains accessible even when the physical office is compromised.

Develop a documented communication protocol for notifying customers, vendors, and key business partners of your operational status after an earthquake. A pre-drafted status communication that can be sent via email within 24 hours of a major earthquake — confirming that key personnel are safe, describing current operational status, and providing a timeline for resuming normal operations — significantly reduces customer attrition during recovery. Test your business continuity plan annually with a tabletop exercise that includes senior leadership, not merely the emergency response team.
