2.16
Personal protective equipment, PPE
Equipment and appliance that prevent personnel and individual from biological, chemical and physical risk agent harm.
2.17
Risk
Integrity of hazard occurrence probability and its consequence severity
2.18
Risk assessment
The overall process to evaluate risk and determine whether it is acceptable
2.19
Risk control
Comprehensive measures adopted for reducing risks
3 Risk Assessment and Risk Control
3.1 Risk assessment and risk control procedures shall be established and maintained in the laboratory to continually carry out hazard identification, risk assessment and necessary control measures. To-be-considered contents include:
3.1.1 If the laboratory activities involve pathogenic biological agents, the biological risk assessment shall be carried out for the laboratory. The following contents shall be considered (but not limited to) for the risk assessment:
a) Known or unknown characteristics of biological agents, such as variety, source, infectiousness, transmission route, susceptivity, incubation period, dosage effect (reaction) relationship, pathogenicity (including acute and chronic), variability, stability in the environment, interaction with other organisms and environment, relevant experimental data, epidemiologic data, and prevention and treatment schemes, etc.
b) If applicable, accident analysis of the laboratory or relevant laboratories;
c) Risk (not limited to biological factors) in the laboratory during the process of conventional and unconventional activities, including activities of all laboratory personnel and other relevant personnel (such as: personnel of the contract part);
d) Risks related to facilities and equipments;
e) If applicable, risks related to laboratory animals;
f) Risks related to personnel, such as physical conditions, ability and pressure that may influence work;
g) Risks caused by incidents and accidents;
h) Misused and maliciously-used risks;
i) Scope, performance and time limitation of risks;
j) Probability assessment of hazard occurrence;
k) Potential hazard and consequence analysis;
l) Acceptable risks;
m) If applicable, control measures and technical measures that eliminate, reduce or control risks, as well as residual risk or new risk assessment after adopting these measures;
n) If applicable, adaptable degree assessment of operating experience and adopted risk control measures;
o) If applicable, emergency measure and anticipated effect assessment;
p) If applicable, input message provided for determining facility and equipment requirements, identifying training requirements and developing operating control;
q) If applicable, assessment for information and resource (including external resource) required for reducing risks and controlling hazard;
r) Comprehensive assessment for risks, requirements, resources, feasibility and applicability.
3.1.2 Risks of activities to be carried out shall be assessed in advance, including chemical hazard, physical hazard, radiation, electrical hazard, flood, fire and natural disaster.
3.1.3 Risk assessment shall be carried out by experienced professional personnel (not limited to the personnel in the organization).
