What is the primary purpose of personal protective equipment (PPE)?
To enhance worker comfort
To reduce production time
To protect workers from hazards
To decorate the workplace
Personal protective equipment serves to shield workers from physical, chemical, and biological hazards. It is an essential safety control measure rather than a comfort feature or decorative element.
Which of the following is a common workplace hazard?
Slips, trips and falls
Noise pollution only
Data entry errors
Poor communication
Slips, trips, and falls account for a large proportion of workplace injuries across industries. While other issues can impact operations, this physical hazard is among the most frequent.
What document outlines standard operating procedures and safety protocols?
Safety signage
Standard Operating Procedure manual
Employee handbook
Incident report form
A Standard Operating Procedure (SOP) manual provides detailed, step-by-step instructions for performing tasks safely. Other documents serve different purposes such as reporting incidents or general workplace policies.
What is the correct method for lifting heavy objects to prevent injury?
Bend knees and keep back straight
Twist your torso while lifting
Keep legs straight and bend at waist
Hold the object away from your body
Bending the knees and keeping the back straight helps maintain proper spinal alignment and reduces strain. Other methods increase the risk of back injuries.
What does an MSDS provide information about?
Emergency contact numbers
Equipment maintenance schedules
Chemical properties and hazards
Employee vaccination records
A Material Safety Data Sheet (MSDS) details a chemical's properties, associated hazards, and recommended protective measures. It does not cover personnel records or maintenance planning.
You observe a forklift operating at high speed in a busy aisle. What mitigation strategy should you implement?
Implement random speed checks
Increase aisle width only
Install speed limiters on forklifts
Paint floor lines instead
Installing speed limiters directly controls maximum forklift speed and reduces collision risk. Other measures may help but are less reliable without an engineering control.
How often should critical instruments be calibrated to ensure accuracy?
According to the manufacturer's schedule
After any repair only
Monthly regardless of use
Only when showing performance drift
Following the manufacturer's recommended calibration intervals maintains instrument accuracy and compliance. Waiting for drift or only after repairs can lead to unreliable measurements.
Which is the first step in a lockout-tagout procedure?
Notify the supervisor
Identify all energy sources
Lock and tag energy sources
Verify absence of energy
Identifying all energy sources ensures that every source is isolated before locking out equipment. Tagging and verification cannot occur until you know what must be controlled.
Which body sets international safety standards for occupational health?
ISO
ANSI
OSHA
ILO
The International Labour Organization (ILO) develops and promotes international conventions and guidelines on occupational safety and health. OSHA and ANSI govern U.S. standards and ISO provides voluntary system standards.
What tool is used to assess the likelihood and severity of identified risks?
Pareto chart
Risk assessment matrix
Gantt chart
Failure Mode and Effects Analysis
A risk assessment matrix maps each hazard by its probability and impact, allowing prioritization of control measures. Other tools serve different analysis or planning functions.
Why are maintenance logs important?
They document equipment condition and maintenance history
They document financial expenses
They track worker attendance
They monitor production speed
Maintenance logs provide a record of work performed, component conditions, and schedules, which is critical for reliability and compliance. They are not designed for personnel or financial tracking.
How frequently should emergency evacuation drills be conducted for compliance?
Every month
Every five years
At least annually
Only after incidents
Conducting drills at least once a year ensures that personnel remain familiar with procedures and meets most regulatory requirements. Less frequent or post-incident-only drills leave personnel unprepared.
What is the first action when a chemical spill occurs?
Evacuate the entire facility immediately
Contain the spill if safe to do so
Leave cleanup to management
Call the press
If it can be done safely, containing a spill prevents spread and reduces hazard level. Full evacuation or media notification are not the immediate first steps in most protocols.
What PPE is most appropriate for dusty environments?
Steel-toe boots
N95 respirator
Earplugs
Chemical-resistant gloves
An N95 respirator filters airborne particles and protects the respiratory system from dust. Other PPE protect different hazards such as chemicals, impact, or noise.
After an incident, within what timeframe should a report be filed to meet compliance?
Before the end of the month
Within 24 hours
Within 7 days
Within 1 hour
Filing an incident report within 24 hours aligns with most regulatory requirements for timely documentation and investigation. Waiting longer can hinder corrective actions.
Recurring machine jams are causing unplanned downtime. What systemic analysis should you perform to identify root causes?
Increase cleaning schedule only
Hire more operators
Conduct a root cause analysis using the 5 Whys
Replace machines annually
A root cause analysis with the 5 Whys method helps trace repeated failures back to underlying process or design issues. Other actions may address symptoms but not the fundamental cause.
Equipment shows increasing vibration trends. What is the best maintenance strategy?
Implement predictive maintenance using vibration analysis
Ignore until a breakdown occurs
Switch to reactive maintenance
Increase lubrication only
Predictive maintenance leverages vibration data to detect bearing or alignment issues before failure. Reactive or lubrication-only approaches do not proactively prevent breakdowns.
You encounter conflicting safety requirements between local and federal regulations. What is the best course of action?
Comply with the stricter regulation
Follow whichever is more convenient
Seek employee consensus
Only follow the federal regulation
Adhering to the more stringent requirement ensures full compliance and risk reduction. Choosing convenience or bypassing stricter rules can lead to violations or increased hazards.
Which engineering control is most effective for containing airborne hazards like gas leaks?
Administrative training
Local exhaust ventilation
Portable gas detectors
Personal protective equipment
Local exhaust ventilation captures and removes contaminants at their source, reducing exposure for all personnel. PPE and detectors are supplementary controls that rely on individual compliance or detection.
Which management system framework integrates safety into organizational processes?
ISO 14001 Environmental Management System
ISO 9001 Quality Management System
ISO 45001 Occupational Health and Safety Management System
OHSAS 18001 Health and Safety Standard
ISO 45001 provides a systematic approach to managing occupational health and safety risks within organizational governance. ISO 9001 and 14001 focus on quality and environment respectively, and OHSAS 18001 has been superseded by ISO 45001.
