Q & A
What is Republic Act 11058 and why is it important for laboratory safety?
-Republic Act 11058 is a law in the Philippines that strengthens compliance with occupational safety and health standards. It ensures that workers are provided with a safe and healthy work environment, including those working in laboratories with hazardous chemicals.
What are the most common ways chemicals can expose workers to health risks?
-Chemicals can expose workers to health risks through inhalation, ingestion, skin exposure, and injection. Inhalation is the most common route, involving exposure to gases, vapors, mists, dust, fumes, and smoke.
Why is eating or drinking prohibited in the laboratory?
-Eating or drinking in the laboratory is prohibited because food and drink can absorb chemical vapors, leading to accidental ingestion of harmful substances. This practice is also banned by the OSH sanitation standard.
What information does a Safety Data Sheet (SDS) provide?
-A Safety Data Sheet (SDS) provides essential information on the properties of chemicals, their hazards, safe handling procedures, storage guidelines, and emergency measures in case of exposure, spills, or accidents.
What do the standardized pictograms on chemical labels signify?
-The standardized pictograms caution users about specific hazards, such as health risks (e.g., cancer, respiratory issues), flammability, skin irritation, pressurized gas hazards, corrosive materials, explosive risks, and environmental harm.
How does the NFPA hazard diamond system work?
-The NFPA hazard diamond uses a color-coded system with four sections: blue for health, red for flammability, yellow for reactivity, and white for specific hazards. Each section is rated from 0 to 4 to indicate the level of risk.
What are the general guidelines for the proper disposal of chemical waste?
-Chemical waste must be properly labeled before disposal, and labels can be obtained from the PUP CS laboratory. The DENR has strict policies regarding the handling of hazardous chemical waste, as outlined in the 2013-22 Administrative Order.
What protective equipment should be used in the lab for chemical safety?
-Lab workers should use appropriate PPE such as lab coats, chemical-resistant gloves, safety glasses with side shields, face shields, and respirators. The type of PPE depends on the specific risks identified during a risk assessment.
How should laboratory chemicals be stored to ensure safety?
-Chemicals should be stored according to their specific hazards. Acids should be kept separate from bases, flammables should be stored in safe containers away from ignition sources, and peroxide-forming chemicals should be stored in airtight, dark, and cool conditions.
What should be done in case of a large chemical spill or emergency in the lab?
-For large chemical spills or emergencies like toxic gas leaks, the area should be evacuated immediately. Close doors and windows, activate fire alarms, and call emergency services (e.g., 911). The incident should be reported to the laboratory supervisor.
Outlines
๐ฌ Laboratory Safety and Chemical Exposure
The first paragraph emphasizes the importance of prioritizing safety in the laboratory. It highlights the risks associated with chemical exposure, such as inhalation, skin irritation, ingestion, and eye damage. It references Republic Act 11058 in the Philippines, which strengthens occupational safety and health standards. This section outlines the dangers of inhaling fumes and stresses the prohibition of eating or drinking in laboratories due to contamination risks. It introduces the role of safety data sheets (SDS) in providing critical information on chemical properties and safety precautions, and details the standardized pictograms used by the Occupational Safety and Health Administration to signify various chemical hazards.
๐ฆ Chemical Storage and Labeling Guidelines
This paragraph explains the proper storage and handling guidelines for different types of chemicals. It covers labeling containers upon receiving or opening them, particularly for chemicals prone to forming organic peroxides. It stresses the importance of separating acids and bases, storing flammables in fire-safe refrigerators or cabinets, and ensuring the accessibility of fire extinguishing equipment. The paragraph also discusses the appropriate storage of oxidizers, peroxides, and compressed gases. In the event of chemical emergencies, such as spills or exposure, first aid procedures and proper response protocols are highlighted to ensure safety.
๐งช Laboratory Requisition and Safety Protocols
This section provides guidance on how to request laboratory equipment and chemicals through both physical requisition slips and the PUP Smart Interactive Technical Assistant (PO SINTA) platform. It explains the steps for obtaining necessary laboratory materials and emphasizes submitting requisition slips at least three days before an experiment. Additionally, the paragraph addresses protocols for replacing broken laboratory apparatus, including obtaining replacements from trusted stores and providing receipts. It also cautions students about the potential consequences of broken apparatus, such as being locked out of the PUP Student Information System (PUPSIS), until the issue is resolved.

stations should be located in rooms or
in hallways prior to your laboratory
activity you must request the things
that you will need in the PCS laboratory
there are two ways you can do so firstly
you may opt to obtain hard copies
requisition slip from the PCS laboratory
there are different kinds of
slips laboratory apparatus requisition
slips are used to request for glass wees
stands and other laboratory
paraphernalia such as hot plates and
water baths laboratory equipment
reservation slips are used to reserve
equipment such as microwave oven
autoclave UV V spectr photometer and
other machinery for use during your
laboratory
session chemical requisition slips are
used to obtain your needed chemicals and
re
agents fill out the information required
in each of these slips and have them
signed by your instructor in charge you
may submit these hard copies to the PCS
laboratory Personnel remember always
submit to slips at least 3 days before
the date of your experiment
alternatively you may choose to utilize
the PO smart interactive technical
assistant or po Sinta for short in this
site you may Avail of various services
offered in our
San including requesting the things you
need for your laboratory activity to do
so go to pup P.S service ops. a or scan
the QR
code log into to your account if you
don't already have an account you may
sign up easily
too once you are in toggle the request
service button scroll down until you
find CS laboratory Main and click here
you may choose what slip you need
according to your needs fill out the
required information and upload a soft
or scan copy of the requisition slips
remember you must also submit this at
least 3 days prior to the
experiment after doing one of those you
can comfortably wait until the day of
your experiment to claim your requested
or served items breaking glass wear or
apparatuses in the love is something we
hope never happens but if it does it's
better to know what to do first replace
the broken item it must be of the same
quality meaning the same brand and
specifications buying your placements
online is not allowed you'll need to get
it from a trusted physical store and
make sure to obtain an official receipt
to submit as proof if you're unsure
consult with the lab supervisor to avoid
any
issues second access lock in pups
student information system or
pupsis until you replace or solve the
broken item you may be locked out of the
upis so it's best to fix the issue as
soon as possible to avoid any problems
with your accounts safety principles
reading and understanding
SDS identify
hazards proper use of
ppes correct preparation handling and
storage of chemicals and glass wear
first aid
procedure and you can now carry out the
experimental procedure you're now
equipped with the knowledge to ensure
safety in the laboratory have a great
and successful experiments and remember
let's work smart and stay safe
