Efficient environmental management is a growing concern in various industrial sectors, and the proper disposal of generated waste is fundamental for preserving the environment and complying with current legislation. When it comes to processes that use particle baths, such as in metal treatment industries, the water used must be disposed of in accordance with specific regulations and standards to avoid negative environmental impacts.

Applicable legislation and regulations

In Brazil, legislation related to the disposal of wastewater and solid waste is quite strict, aiming to minimize environmental impacts and ensure public health safety. Specifically in São Paulo, Decree 8468 of September 8, 1976, and Law 997, regulated by CETESB, are the main instruments guiding the proper disposal of these wastes.

Decree 8468/76 and Law 997

Decree 8468/76 establishes the rules for pollution control and waste management in the state of São Paulo, highlighting the obligations of industrial companies regarding the treatment and final disposal of effluents. The Decree is complemented by CETESB Law 997, which, in article 18 and its sub-articles up to article 19-A, determines how wastewater and solid waste from industrial processes, including particulate baths, should be treated.

CONAMA Resolution No. 20/86

In addition to state regulations, CONAMA Resolution No. 20, of June 18, 1986, is extremely important. Article 21 of this resolution establishes general guidelines for the treatment and disposal of industrial wastewater, focusing on the prevention of pollution of surface and groundwater. Together with other legislation, the CONAMA Resolution provides guidance on the need for efficient treatment processes and on how to obtain the necessary environmental permits for proper disposal.

NBR 10004 and waste classification

Solid waste generated in the particle bath process must be characterized according to NBR 10004, which classifies waste into different categories according to its hazardousness. For magnetic particle waste, the classification is class II, i.e., non-inert waste. This classification is relevant because it determines the method of storage, transport, and final disposal of the waste, according to its potential impact on the environment.

Procedures for the treatment and disposal of waste.

The routine for treating and disposing of effluents in particle baths must follow a well-established procedure, ensuring that all legal requirements are met. Below, we detail the suggested steps for the proper treatment of the residual solution.

Treatment procedure steps:

1. Solution preparation : For 1000 ml of residual solution from the particle bath, the following reagents should be added: 50 ml of 5% lime solution, 50 ml of 10% aluminum sulfate solution, 15 ml of 0.5% polyelectrolyte solution.
2. Reaction time : After adding the reagents, it is necessary to wait 30 minutes for flocculation and sedimentation of the contaminant particles to occur.
3. Filtration and drying : The solution must then be passed through a filter press or drying bed to separate the solids from the wastewater. This process aims to concentrate the solid waste, which will later be disposed of in accordance with regulations.

Disposal and required documentation

To dispose of treated water and solid waste, the company must be aware of the need to obtain an “acceptance letter.” This document is issued by a specialized company, such as a reprocessing plant, landfill, or incinerator that has authorization from the state environmental agency to receive the waste. With the acceptance letter in hand, the company can then request the CADRI (Registration of Waste of Interest), which is an authorization from the environmental agency to dispose of the waste at the authorized location.

This procedure ensures that waste will be treated and disposed of properly, avoiding risks to public health and the environment, and complying with legal requirements. Failure to comply with these regulations may result in severe penalties, including fines and even the closure of the company.

Proper management and adequate disposal of waste generated in particle baths is a critical issue for environmental sustainability. Following current regulations and guidelines is not only a legal obligation, but also a social and environmental responsibility of companies. With proper treatment and disposal of waste, it is possible to minimize environmental impacts and ensure compliance with legislation, as well as promote a safer and healthier environment for all.

Do you know what GHS means?

The GHS, or Globally Harmonized System of Classification and Labelling of Chemicals, is an international system for classifying and labelling chemicals in a standardized way. Its objective is to ensure clear communication about the hazards of chemicals, promoting safety at the workplace and during transport.

The GHS establishes harmonized criteria for classifying chemicals according to their physical, health, and environmental hazards. The classification criteria are based on available data on the chemicals and on predefined hazard criteria.

The GHS includes standardized elements for labels and safety data sheets, such as pictograms, signal words, hazard statements, and precautionary statements. The GHS is valid for all chemicals, except those already regulated by their own laws or regulations.

To ensure chemical safety, it is important that everyone involved, such as manufacturers, suppliers, employers, and workers, are committed.

According to UFPEG, the GHS is not a regulation. The instructions presented provide a mechanism to meet the basic requirement of any hazard communication system, which is to determine whether the manufactured or supplied chemical product is hazardous and to prepare an appropriate label and/or SDS (Safety Data Sheet).

The GHS document, also known as the “Purple Book,” consists of technical requirements for hazard classification and communication, with explanatory information on how to apply the system.

The GHS document integrates the technical work of three organizations: ILO, OECD, and UNCETDG, with explanatory information. It provides building blocks or deployment modules for regulatory bodies to develop or modify existing national programs that ensure the safe use of chemicals throughout their entire life cycle.

The GHS was introduced in Brazil through the ABNT NBR 14725 series of standards, divided into 4 parts ranging from classification to labeling and preparation of SDSs (Safety Data Sheets) for chemical products. In 2011, with the revision of the NR26 labor regulatory standard, the GHS became the official system for the classification and labeling of chemical products.

For the safe management of chemical products, workers and consumers need to become familiar with the pictograms and hazard statements introduced on labels by ABNT NBR 14725, with the aim of alerting the user to the dangers and thus minimizing the risk of accidents and exposures.

What are the hazard classes in the GHS?

Physical Hazards:

Explosives; Flammable gases; Flammable aerosols; Oxidizing gases; Gases under pressure; Flammable liquids; Flammable solids; Self-reactive substances; Pyrophoric liquids; Pyrophoric solids; Self-heating substances; Substances and mixtures which, in contact with water, emit flammable gases; Oxidizing liquids; Oxidizing solids; Organic peroxides; Corrosive to metals.

Health Hazards:

Acute toxicity; Skin corrosion/irritation; Serious eye damage/irritation; Respiratory or dermal sensitization; Germ cell mutagenicity; Carcinogenicity; Reproductive toxicity; Systemic target organ toxicity – single exposure; Systemic target organ toxicity – multiple exposures; Aspiration hazard.

Environmental hazards:

Potential for bioaccumulation and rapid degradability.

At Metal-Chek, we are committed to the strict application of GHS guidelines. We value safety at every stage of the lifecycle of the chemicals we handle, from manufacturing to transportation. Our mission is to ensure not only regulatory compliance but also the protection of health and the environment. We believe that effective GHS implementation is crucial for developing a safety culture, and we will continue to invest in training and awareness for everyone.

Magnetic particle testing (MPT) is widely used in industry for the detection of surface and subsurface discontinuities in ferromagnetic materials. This method combines the magnetization of the material with the application of magnetic particles to visually and accurately identify flaws, standing out for its ability to detect flaws with precision and efficiency.

The basic principle of magnetic particle testing is the formation of a magnetic field in the material under inspection. When a discontinuity, such as a crack or non-magnetic inclusion, interrupts this magnetic field, a leakage field is created. This leakage field attracts magnetic particles applied to the surface, forming a visible indication of the defect. This mechanism allows the method to be widely recognized for its efficiency and accuracy in identifying discontinuities.

Inspection Process

1. Surface Preparation: The material surface must be clean and free of contaminants such as oils, greases, and other residues that may hinder detection.
2. Magnetization: A magnetic field is applied to the material using one of the following techniques:

• Direct current (DC or AC).
• Magnetization by coils or electromagnets
• Magnetization by contact with magnetic yokes.

3. Application of Magnetic Particles: The particles can be applied in the form of dry powder or liquid suspension (water- or oil-based). Fluorescent particles, visible under UV light, are ideal for inspections requiring high sensitivity.

4. Observation and Interpretation: The surface is inspected for particle accumulations that indicate the presence of defects. In the case of fluorescent particles, a UV lamp with appropriate intensity is used, such as those meeting ASTM E3022. This step is fundamental to ensure that defects are detected accurately and efficiently.

5. Demagnetization and Cleaning: After testing, the material must be demagnetized to avoid future interference in its use, and cleaned to remove any applied particles.

Advantages and Limitations

The advantages of magnetic particle testing include the detection of both surface and subsurface discontinuities, simplicity and speed of application, high sensitivity, especially with fluorescent particles, and a relatively low cost compared to other non-destructive testing (END) techniques. Limitations of the method include its restriction to ferromagnetic materials, the need for direct access to the surface to be inspected, and the possibility of false positive results due to particle accumulation in complex geometric regions.

With all this in mind, we know that currently, magnetic particle testing is an essential tool for ensuring the integrity and safety of critical components in a wide range of industries. Its proper use, combined with advanced technologies such as high-intensity UV lamps, contributes to the precision and reliability in fault detection. And Metal-Chek strives to ensure that such results are always guaranteed with maximum efficiency.
