Electronics & Semiconductor EHS & Safety Management Software

Connect chemical safety, process-tool hazards, occupational exposure, contractor work, and environmental compliance across electronics and semiconductor operations.

Semiconductor fabrication, printed circuit board manufacturing, electronics assembly, and device testing present different EHS requirements. Wafer fabrication may involve toxic gases, corrosive chemicals, and hazardous process residues. Electronics assembly introduces soldering fumes, cleaning agents, repetitive precision work, and electrical testing hazards.

Dexur EHS connects incidents, inspections, exposure concerns, investigations, and corrective actions to the process, equipment, chemical, and task involved. Help EHS, facilities, process engineering, equipment maintenance, and production teams coordinate follow-up across cleanrooms, support areas, assembly lines, and laboratories.

Manage Safety Across Process Tools, Chemicals, and Facility Systems

In semiconductor manufacturing, the conditions inside an enclosed process tool can differ substantially from those encountered when the tool is opened for maintenance.

Chamber cleaning, vacuum-pump servicing, exhaust maintenance, gas-cylinder changes, and chemical-line work can expose personnel to hazards normally contained during production. Changes in process chemistry can also alter the residues, exhaust loads, and waste streams that maintenance and facilities teams must manage.

Electronics assembly has a different operating profile. Soldering, rework, adhesive dispensing, board cleaning, inspection, and electrical testing require task-specific exposure controls and work practices.

Identify Hazards by Process and Activity

Relevant concerns include:

Toxic, flammable, pyrophoric, or corrosive gases used in certain fabrication processes
Hydrofluoric acid and other corrosive chemicals used in applicable wet-processing operations
Solvents, photoresists, developers, adhesives, and cleaning agents
Hazardous deposits in process chambers, vacuum lines, pumps, and exhaust systems
Oxygen displacement from nitrogen, argon, and other inert gases
Chemical exposure during delivery-system maintenance and container changes
Electrical hazards and stored energy in process tools and test equipment
Heat, ultraviolet radiation, lasers, or other radiation sources where present
Flux fumes and contact with soldering materials during assembly and rework
Repetitive microscope work, precision assembly, and awkward tool-maintenance access
Chemical incompatibility in waste collection and drainage systems
Concurrent contractor activity during tool installation and facility expansion

These hazards vary by process. A surface-mount assembly line should not inherit the same chemical-risk assumptions as a wafer-fabrication operation. OSHA identifies distinct hazards across semiconductor manufacturing activities. OSHA: Semiconductor Safety Overview

Connect the Process Change to the Safety Follow-Up

Dexur EHS supports a connected workflow:

01

Identify
02

Investigate
03

Prioritize
04

Assign
05

Correct
06

Verify

Associate each finding with:

Process Area → Tool or Workstation → Chemical or Energy Source → Task → Responsible Team

For example, a chamber-maintenance exposure concern may require review of process residues, decontamination methods, ventilation, protective equipment, and waste handling.

A recurring soldering-fume complaint may require assessment of extraction placement, airflow, flux chemistry, and actual rework practices.

The record should show which conditions were evaluated, what changed, and how the correction was verified.

One unified platform

Coordinate EHS Across Fabrication, Assembly, and Support Operations

01 / INCIDENTS

Incident & Near-Miss Management

Capture chemical events, gas-system concerns, equipment incidents, exposure reports, and near misses across production and maintenance.

Preserve the distinction between an alarm, a confirmed release, a suspected exposure, and a verified injury. Each can require different investigation and follow-up.

Industry-specific use cases include:

A gas-detection alarm during a cylinder change
A chemical splash during wet-bench servicing
Unexpected residue encountered when opening a process chamber
Loss of local exhaust at a soldering or chemical-handling station
An oxygen-deficiency alarm in a support area
Unexpected tool motion during maintenance
An electrical incident during board or equipment testing

02 / INSPECTIONS

Inspections & Hazard Management

Organize inspections around the process tool and the systems supporting it.

Inspection topics can include:

Gas cabinets, valve enclosures, and chemical-delivery areas
Wet benches and chemical-transfer connections
Exhaust connections and evidence of ventilation deficiencies
Process-tool access panels, guards, and interlocks
Hazardous-energy isolation arrangements
Vacuum pumps and maintenance work areas
Chemical storage compatibility and secondary containment
Soldering and rework extraction
Waste containers, collection connections, and identification
Service access, lifting aids, and workstation ergonomics

Attach findings to the affected tool, support system, or workstation. This makes it easier to distinguish a local equipment issue from a shared facilities problem.

03 / COMPLIANCE

Compliance & Exposure Records

Organize documentation supporting applicable workplace safety programs.

Connect:

Chemical inventories and safety data sheets
Task-specific exposure assessments
Air-monitoring results and follow-up actions
Respiratory protection program records
Hazardous-energy procedures
Chemical and gas-handling training
Emergency planning documentation
Equipment safety assessment findings
Injury and illness records
Contractor orientation and work-coordination records

Cleanroom clothing and electrostatic-discharge controls serve particular operational purposes. Their presence does not establish that chemical, respiratory, or electrical protection is adequate for a task.

04 / CORRECTIVE ACTIONS

Corrective Action Management

Assign actions to the team responsible for the underlying condition.

Examples include:

Correcting an exhaust connection serving a wet-process tool
Revising a chamber-cleaning procedure after a chemistry change
Addressing recurring leaks at a chemical-transfer connection
Improving access for vacuum-pump maintenance
Correcting an incomplete isolation procedure
Repositioning solder-fume extraction
Resolving incompatible waste-collection arrangements
Updating contractor hazard information before tool servicing

Finding → Affected Tool or System → Risk Priority → Owner → Correction → Verification

Record the evidence needed to close the action, such as an inspection, exposure reassessment, functional check, or documented procedure review.

Electronics & Semiconductor Incident Reporting and Compliance Records

Capture Events With the Right Process Context

Relevant incident and near-miss categories include:

Corrosive chemical splashes and contact exposures
Suspected inhalation exposure during chemical handling
Toxic or flammable gas releases
Pyrophoric-material events where such materials are used
Oxygen-deficiency alarms and inert-gas releases
Process-chamber or exhaust-residue exposure
Chemical reactions involving incompatible materials
Vacuum-line or pump-maintenance incidents
Electrical shock and stored-energy events
Thermal burns from heated tools, ovens, or soldering equipment
Laser, ultraviolet, or other radiation-related concerns where applicable
Flux-fume complaints and exposure concerns
Repetitive-strain injuries during precision assembly and inspection
Equipment-handling incidents during installation or removal
Waste-collection leaks and environmental releases

Document the Conditions at the Time of the Event

Capture:

Facility, cleanroom bay, subfab area, laboratory, or assembly line
Tool, chamber, workstation, and supporting-system identification
Process step and operating state
Production, maintenance, installation, or decommissioning activity
Chemical or gas identity and available concentration information
Relevant process or maintenance history
Employees, contractors, and witnesses involved
Isolation, purge, and decontamination status where relevant
Ventilation, abatement, and gas-detection conditions
Alarm and response timestamps
Exposure route and reported symptoms
Immediate controls and access restrictions
Photographs, maintenance records, and investigation evidence

Retain the source and context of measurements. An area alarm, a personal exposure sample, and a maintenance observation answer different questions.

Connect Investigation to the Systems Involved

Event → Process and Task Review → Equipment and Facilities Review → Exposure Assessment → Corrective Actions → Verification → Closure

A gas-system event may involve the cylinder connection, distribution equipment, detection system, exhaust, procedures, and service activity.

A chamber-opening concern may involve residues from previous processing, incomplete decontamination, or assumptions based on an earlier process chemistry.

The investigation should establish which systems and work practices contributed, then assign the corresponding actions.

Match OSHA Requirements to Electronics and Semiconductor Work

Requirement	Industry application	Records and follow-up

Evaluate applicability by task, substance, and process. The use of hazardous gases alone does not establish that every fabrication process is covered by PSM. OSHA: Semiconductor Standards

Apply Substance-Specific Standards Carefully

Certain operations may require assessment under substance-specific rules, including OSHA’s lead or inorganic arsenic standards.

The inorganic arsenic standard, 29 CFR 1910.1018, expressly excludes arsine from its scope. Arsine hazards therefore require evaluation under the applicable exposure limits and other relevant requirements rather than treating all arsenic-containing substances identically. OSHA: Inorganic Arsenic

For electronics assembly, determine the composition of solder and other materials actually used. A lead-free solder designation does not resolve separate questions about flux emissions, cleaning solvents, or thermal hazards.

Distinguish Regulatory Requirements From Equipment and Quality Standards

Framework	Primary purpose	Relationship to EHS workflows
OSHA workplace requirements	Employee safety, exposure control, safe work practices, and occupational records.	Manage workplace findings, incidents, assessments, and corrective actions.
SEMI safety guidelines	Equipment-related EHS evaluation, risk assessment, ergonomics, ventilation, and other semiconductor-specific topics.	Track assessment findings and responsible technical follow-up where the guidelines are adopted.
Cleanroom classification and contamination-control requirements	Control the manufacturing environment for process and product needs.	Coordinate shared facilities issues while separately assessing employee exposure and protection.
Electrostatic-discharge control requirements	Prevent electrostatic damage and control specified electrostatic risks.	Review compatibility with task-specific electrical and chemical safety arrangements.
Product material restrictions and customer specifications	Establish requirements for substances or characteristics of delivered products.	Refer relevant concerns to product-compliance owners; retain separate workplace exposure assessments.
Environmental requirements	Control applicable emissions, wastewater discharges, hazardous waste, and reporting.	Organize facility-specific obligations, evidence, findings, and actions.

Relevant SEMI guidelines include S2 for manufacturing-equipment EHS, S6 for exhaust ventilation, S8 for equipment ergonomics, S10 for risk assessment, and S12 for equipment decontamination. These are industry guidelines whose contractual or other applicability should be established; they should not be presented as universally mandatory OSHA regulations. SEMI: Safety Standards

Organize Environmental Compliance by Process and Permit

Air Emissions

Covered semiconductor manufacturing operations may be subject to 40 CFR Part 63, Subpart BBBBB, alongside applicable air-permit requirements.

Connect required monitoring and records with solvent use, process exhaust, and emission-control equipment where relevant. EPA: Semiconductor Manufacturing NESHAP

Wastewater

40 CFR Part 469 contains effluent requirements for specified electrical and electronic component manufacturing operations. Coverage depends on the regulated activity, not simply an “electronics” industry label.

Track the applicable discharge limits, sampling points, treatment findings, and corrective actions. Other processes, including certain metal-finishing activities, may require separate applicability review. EPA: Electrical and Electronic Components Effluent Guidelines

Greenhouse Gas Reporting

Facilities meeting applicable criteria may have reporting obligations under 40 CFR Part 98, Subpart I—Electronics Manufacturing.

Maintain the relevant process-gas and supporting records according to the facility’s reporting determination. EPA: Electronics Manufacturing Greenhouse Gas Reporting

Generate Reports That Reveal Process-Specific Issues

Useful reports include:

Chemical events by material, tool, and task
Gas alarms categorized by investigation outcome
Maintenance exposure concerns by chamber or equipment family
Repeated exhaust or abatement findings
Exposure assessments awaiting follow-up
Contractor findings during installation and service
Actions outstanding after process changes
Environmental excursions associated with particular tools or waste streams
Recurring ergonomic concerns at inspection and rework stations

Find the Connections Between Tool Events and Shared Systems

A finding at one tool may originate in a shared exhaust, gas-delivery, chemical-distribution, or waste-treatment system.

Conversely, several events involving the same tool family may reflect a common maintenance-access problem or an incomplete understanding of process residues.

Review risk across both equipment and supporting infrastructure.

Ask Questions That Reflect Electronics and Semiconductor Operations

Which tools have unresolved exhaust or chemical-containment findings?
Are gas alarms recurring during the same cylinder-change activity?
Have maintenance procedures been reviewed after a process-chemistry change?
Which chambers generate repeated concerns about residual contamination?
Are multiple tools affected by the same facilities-system deficiency?
Which exposure assessments require control improvements or reassessment?
Are soldering-fume concerns concentrated at specific rework stations?
Which contractors are waiting for complete decontamination information?
Are waste-treatment excursions associated with a particular process or discharge pattern?

Prioritize Exposure Potential and Control Reliability

Consider toxicity, quantity, release potential, task frequency, occupancy, and the status of protective systems.

Give attention to unresolved high-consequence conditions even when normal production is enclosed and injury rates remain low.

Tool Findings + Exposure Assessments + Gas Events + Maintenance History + Facilities Deficiencies + Process Changes→Identify the Affected Tasks and Systems→Evaluate Potential Exposure and Consequences→Assign Controls and Technical Follow-Up→Verify Under Relevant Operating Conditions→Review Similar Tools and Shared Infrastructure

Dexur’s role is to organize findings and follow-up. Gas detection, equipment interlocks, and emergency shutdown functions remain with the designated engineered safety systems.

Measure Exposure Prevention and Control Follow-Through

Combine occupational injury measures with indicators showing whether critical findings, maintenance hazards, and exposure concerns receive timely attention.

KPI	What to measure	Electronics & Semiconductor application
OSHA TRIR and DART Rate	Recordable cases and cases involving days away, restricted work, or job transfer, normalized by hours worked.	Compare fabrication, assembly, maintenance, and support operations with appropriate workforce context.
Chemical and Gas Event Frequency	Confirmed releases, suspected exposures, and investigated alarms, reported as distinct categories.	Identify patterns by chemical, gas system, tool, and task without equating every alarm with an exposure.
Exposure Assessment Follow-Up	Assessments completed, required controls outstanding, and reassessments due.	Monitor chamber maintenance, wet processing, soldering, cleaning, and other exposure-sensitive tasks.
Critical Inspection and Test Completion	Scheduled checks completed and deficiencies resolved, based on records from responsible teams.	Track follow-up for gas systems, exhaust arrangements, chemical delivery, and designated protective equipment.
Open High-Priority Tool and Facilities Findings	Number, age, affected systems, and interim-control status.	Identify unresolved containment, exhaust, hazardous-energy, and chemical-handling concerns.
Verified Corrective Action Performance	On-time closure, overdue actions, verification completion, and repeat findings.	Determine whether technical changes addressed the original condition and remained effective.
Contractor and Maintenance Readiness	Required hazard reviews and handover documentation completed before applicable work.	Track decontamination information, isolation coordination, and task-specific preparation for service activities.

Use suitable activity measures where available, such as maintenance interventions or cylinder changes, when interpreting event frequency.
